Judging Jack Distance 2/5


By calling this "The Baseball Method" of evaluating the "Jack Distance", I believe, the reader will remember that the baseball player has an instinctive feeling of his needed distance. (which is what this method of distance evaluation is really)
The baseball player has developed this feeling, over years of training and game play; where he has always tried to accurately throw the baseball to that precise distance needed for a great play. In a similar manner lawn bowlers have developed an instinctive ability to roll the Bowl to the Jack distance they feel.

How the brain might judge an object's distance, whether by using Vision Preception, Times Elapes  (of moving objects) , Revision of Action/Results would be a long blog. It is best to suggest the reader google these actions.

However, the brain is a lazy organ which does not want to repeat the same thing several times; and therefore our subconscious makes judgments from what it  has previous seen and done. This blog and its sister (blog 3) will attempt to define the errors this laziness has caused and how the developing bowler should work to re-educate or program the subconscious so instinctive actions are based on information that has been changed and now is accurate.

In the "Baseball player" example we only looked at the physical action and the minds' instinctive ability to throw the ball. What made the profession outfielder is a lot of other things and other decisions. He would not have caught the coming ball without evaluating the speed and his expectations of the bounces. His decision to throw to second base involves a "Open Sport" analysis (Bowls is a "Closed Sport") as he remained open to everything happening around him. His judgement on how far, and how much energy he needed may also have meant learning about the stadium in which he was playing. Left field may be an extra 30 feet as to his own Stadium.

 All of these things he has calculated in a  fraction of a second and the muscles and instinct have made the required delivery. His feedback as he watches his ball go to where it was intended; thrown with all the experience of years, now  provides new information to the subconscious mind for the next time this instinctive throw is needed.

You win the coin toss and you have a choice to take the mat  or give the mat away.  It would be nice to have the last bowl. What do you do? You make the decision based upon your knowledge of your "Lead". Your team must have been build on the ability of your lead to throw the "Jack" and draw a "Bowl" to its location. How does the lead do this ? Distance Evaluation ? or Performance ?
Rebecca Van Asch

Why mention the "Lead" on a "Judgement of Distance" blog ? Because any skills of "Instinctive Draw" and a delivery has to be based upon a proper evaluation of the jack Distance. When you started lawn bowls, and probably as a "lead"; your mind began, on the first day; collecting information on evaluating the "Jack Distance". With each "Jack" delivery or "Bowl" delivery the mind has added more information.  Photo (left) from 2018 Australian Indoor Championship Woman Singles. Both players, Rebecca Van Asch and Chloe Stewart (behind) watch the jack as it is rolled up the green.
 As a beginner and you watch the jack go up the green, but did you tell your subconscious  mind: What to watch? how to measure?, and what information is available and how to use it ? What you think, will become instructions to the subconscious, so be thinking while you watch the jack roll.
If nothing, what did the mind see and analysis?

In your first year of bowls, did you always count the jack speed like you later learn to count the bowl's;  to know the green speed? The mind is collecting information on distance and a good count helps evaluate distance; otherwise the mind will only get a feeling.."It feels short" "It feels Long" or a lazy mind "I don t feel anything".
 The count does not matter (don t remember the number); it is just teaching a lazy mind to watch and calculate as the jack rolls. Better than the new player who turns to go get their bowl as the jack is rolling; because later as the bowler develops, more refined an "Instinctive Draw", the subconscious will  still needs a habit of collecting precise information.

 The problem is. Like any computer machine without instruction, and the mind is an organic computer;  the subconscious mind will made decision based on  bad or missing information. Today, regardless of your type of Distance Judgement, the subconscious is still developing its method of an evaluation of distance and how to perform a perfect delivery roll to that distance. 

In https://www.verywellhealth.com/ while talking about "Motion Parallax" Dr Tony Bedinghaus   writes. "your brain uses the information to help determine distances."  One of the most valuable tools of distance determination for the lawn bowler, is the speed and roll of the jack. Unlike a baseball which is stopped by a catch, the Jack is stopped by the friction of the green and the harder it is thrown the farther it goes.. (by the way, Motion Parallax does not apply in Bowls because it refers to left/right movement of the head as vision information is collected about several distance objects and analysis by the brain for distance. But, the "Motion Analysis" of the jack as it rolls up the green does offer a lot of

information ) 


Have you ever heard said " Jack and Bowl makes 30" ?  If I was coaching on the side of the green, I would wait while you think and analysis what it might mean. You will notice with both Australian players that they are waiting at the mat with their bowls as the jack is rolling up the green and placed. (In the photos Van Asch has her bowl beside her, Arron Wilson (above) has picked up his bowl and is ready when the jack is placed)

Instinctive Bowlers know that if the Bowl is delivered within the 30 seconds after the jack delivery; the mind and body Subconsciously remembers (Muscle Memory) the energy used to throw the jack; and then repeats this energy with the Bowl delivery. All works together and allows the player to draw to the jack with their first Bowl.  Below, we see Canadian bowler, Ryan Bester during the 2018 Commonwealth Games Singles Final against Arron Wilson from Australia; with bowl in hand as throwing the jack. This video now (May 2020) available on Bowls Australia Facebook as their FlashBack Friday video of the GC2018 Rewind Video SeriesAnother good habit to develop.

If I was to go out to the green with a golf ball, a jack and your bowl and told you to throw each one with your Natural Delivery force or weight what would you say?  What would you think would be the result ? Have you tried it ? Why not ?

The principle of the Natural Delivery is that you make all the same movements every time and it results in the same energy being developed and put behind your bowl. This is a collection of energy from the Pendulum swing, body movement, balance, green speed; all combined to create an instinctive delivery.  Call this energy Send Force and Green speed or lack of it as Green Friction. When you attempt to put the same energy to three objects of different size they take only what energy they can collect and the rest of the delivery "Send Force" remains in your arm. (sore arm from throwing the golf ball) The Send Force is now divided between delivery force to the ball and rejected force felt as a sore arm from throwing the smaller golf ball.  Try other balls of different weights.  (The lighter the object the more rejected force and muscle backlash) 

Yes, all three balls will go the same distance if you don t allow the subconscious mind to think that the smaller and lighter therefore must need less to go that same distance. Remember your subconscious is trying to use it knowledge of distance and give you an analysis of what you need.  You, on the other hand is  just trying to do a Natural Delivery with different objects. Don't think Bowls and that you are on the green; instead  think.. "This is an experiment" telling the mind.. Out of here

 Why?  I believe that the  the  grass friction applies differently  to the weight of the object  ball and this Green Friction change by the object size needs less energy of the Delivery. But with the same Natural Delivery  energy it will be harder with the smaller object to do that energy.. Each ball will not take the same energy storage to the ball and it will result in the same distance. 

The reason your arm hurts with the golf ball is your natural energy tries to do the same but finds because of the ball size it can not. Try it. But remember use the same delivery weight and don t think of anything but doing a perfect delivery. Your mind will want to attempt to make an adjustment and this is you taking charge of the lazy computer of a mind (subconscious).

So this Baseball Method of knowing what is the jack distance is not a measure of say "27 meters" but an instinctive feeling or ability of the subconscious to gather a feeling for the distance and than  do a  delivery with a sufficient energy, The mind will even adjust as new information is being gathered. (you now watch the jack roll, and use clues of how far the jack is  away, as learned in the next blog). Or maybe even now, you have started to do your delivery  within that 30 seconds between jack delivery and your perfectly delivered bowl and your subconscious is learning something new.  

A good exercise here is to go to the green with 4 jacks and do 4 Jack/Bowl in 30 to develop this ability of quickly following the jack. and now your subconscious with its Muscle memory results in a better delivery. When you see the difference in results you have made the  first step. Now  the next step is to feel the muscle memory feeling and know of your bowl's success.

Now for the problem.  You have finished your first bowl and leave the mat.. A minute later you come back to the mat to roll a 2nd bowl... How does that Instinctive Bowl find the jack distance?  How do you gather the subconscious into a state of readiness which will give the same result as the first bowl.

The biggest problem is that the mind is lazy and subconscious delivery does always what it want to do.. You must make the mind work to gather and hold the information and must teach the Instinctive Bowl that is delivered  by the subconscious mind, to change and do what you want it to do.  Not what it wants to do.  How?  I will attempt to explain some tricks in the next blog.
