Torgerson BTM 08/08 article...
« on: September 10, 2008, 05:29:57 AM »
"Match the MB or diff-flare to your game" is the title, I'm pretty sure someone here have read this article...

Torgerson talks about MB/diff related to rev rate and speed... low, med, high... my question here is there a "table" where I can check how much is considered "low/med/high" revs and speed related?

Thanks!

In BTM, the balls under 4.0 are considered low diff/flare or RG.
The balls 4.0-6.9 are considered medium.
7.0 and up is considered high diff/flare potential or high RG.

Thanks "IronMan"...

The values you mention are clear to me... the revs and speed are the ones I want to know...

How do I know how much is "low/med/high" revs and speed in player?

Example... if I have 280 rpm, is this low?, med? high?, If I throw 20 mph is this slow, med, fast?

I'd say anything uder 275 is low.
275-375 is medium.
375+ is high revs.

Speed 14 mph and under is slower.
14-17.5 mph is medium.
17.5 and up is fast.

Also remember a big booming hook can throw off the speed indicators on modern scoring units.
Because the quickest speed will always be a straighter shot over a hook on these systems.

Tuning the ball's potential to the player's needs is a diffcult task. There are many variables in the equation - just the core position, relative to the player's PAP and taking into account speed, rev rate, RG, differential, coverstock strength an preparation, lane condition including oil pattern and volume, lane surface and probably even air humidity and temperature, needs IMO careful consideration if you want to achieve a certain reaction and utility. Esp. the pin position, which defines when and how much of the core' stored energy is used on the lane, is IMHO a very touchy thing that has big impact on ball effectiveness. Remember - the "best" ball is one that just gets into its final roll phase, with the core in its stable end position, before it enters the pins. That's the goal in order to exploit ba ball's potential.
