Re: Re: Re: My Calculations

>>> Jack and BHL, I wish you two could hash out the comparisons and contrasts of your views on this subject. I think it would be enlightening to all. In the interest of having a serious discussion, though, I would request the webmaster to not allow the discussion to be interupted with side issues, insults, etc. It would be great for others to join in the dialog, but it would be helpful to the dialog for the webmaster to be very cautious in allowing posts that are even in the slightest sarcastic, irrelevant, mean-spirited, etc. Allowing one sarcastic comment to be posted results in someone else wanting to "get even". Let's just hash this thing out based on a relevant and respectful dialog.

The bottom line is what I stated in a post below. --- “BHL believes all hitters should be taught to pull all pitches. - I believe that although great hitters have mechanics that allow them to successfully pull outside pitches, the swing mechanics used by most hitters would breakdown when attempting to pull balls on the outer part of the plate.

Early tomorrow morning, I will post the specific calculations. I can't wait until tomorrow...

We will see that, by keeping the rate of angular displacement at a constant (i.e., 225 degrees), the batter need only widen the circumference of bat-head rotation to ensure that he or she can hit to the “natural” field with regularity.

My recommendation is that he or she stand at least 34 inches off the back edge of the inside corner. Now, many individuals are going to posit that such a move will make it more difficult to hit outside pitches. If we put geometry before instinctual criticism, the distance of the plate with actually force the batter to realize that, in order to be successful, the bat-head must be accelerated in a circle.

Functionally, though, the hitter would most likely hit pitches in which the bat head swept in arc tilted 45 degrees to the ground.

Hence, the bat-head will travel out half the length of a seventeen-inch plate, or 8.5 inches, which, when added to 34 inch bat, increases the lever-arm to 42.5 inches.

This means that all pitches can be pulled. It is advantageous to use this modality all the time.

Jack, can we get the dialog back on track? One person has dismissed BHL's calulations without commenting on any specific disagreement with his calculations. Another person has suggested that BHL has made a a good case. What I would like to see is YOUR evaluation of his calcs.I would love to see other people's evaluation as well, as long as the evaluation addresses specifics of his math & not just a general agreement or disagreement. This is a golden opportunity for us to discuss FACTS (pro or con) for once instead of the same old stuff about personalities, credentials, etc.BHL has made a presentation based on math & science, now Jack, can you lead the way in evaluating his analysis based on science and math? Thanks so much, let's have a great discussion!
