I am posting this here as all to often I see people throwing a number out at a point of reference for soliciting help. For those that have posted a RPM number, is it official or unofficial. I know my official CATS number, that's why I am curious.

The left sucks & the right is wide open! R.I.P. Brizmo 6/15/08

a lot of people seem to think im up around 400, im thinking its closer to 300-325.

Never know

Shawn

People tell me I'm somewhere between 150-500

i think im between 1-2
--------------------
Im so glad people are brainwashed to think that TRACK sucks. And its even funnier when im carrying with my TRACK ball and they're going flat ten with their BRUNSWICK ball.

Part of my reasoning on this comes from Osku and Belmo being tracked in the low 600's. Given that I feel like a little girl bowling next to them I figured I can't be within 100 lol.

LOL. Yeah seems to be the only patterns I can play on at the moment! Its more about hating what blocks do for the game

Riggs,

Isn't that release hard to control or hang on to the ball?

Just leave it in the car or at home.

You can use the following method to more accurately calculate your rev rate:

Find and mark your PAP with white tape (or a contrasting colour to your ball colour) and make a line with tape from your PAP to just above your ring finger hole. Set a video camera down on the approach to get the right level for videoing the ball motion and tape yourself throwing a shot.

Play back the video using software that allows you to advance one frame per click and time how long it takes the ball to complete 1 revolution. Divide that time (in seconds) by 1 to find your revs per second, then multiply by 60 to get it into RPMs.

For this method to be successful you not only need software that can play one frame per click, you need to take video in as high a frame rate (FPS) as possible in order to not miss time. I used this method yesterday, but I only get 15FPS out of my camera so it was nowhere near accurate enough. I timed for 1 second and had somewhere in the region of 8-8.25 revs in that time. I needed to use that much time to balance out the error caused by the low frame rate, but in doing so 1 second is too much time to measure true hand revs as the ball has likely encountered some friction by then and/or the core has taken over and has helped the ball rev up somewhat.

With a better camera this is the most accurate way to measure rev rate, even better than CATS because it does not rely on calculations involving speed and ball position (which have inherent errors - as exposed by throwing a plastic hard at the 10pin during a CATS test )

Although inaccurate, I found somewhere in the region of 480-500 RPM for myself, but adjusting for the fact the core had come into affect, I would say 450 is a fair estimate. FYI I used a T-Road Pearl for the test, if somebody out there is estimating the core affect the RG is 2.57.

I know, I'm a geek... Anybody want to chime in, feel free.
