G'Day Folks,
This was asked of me the other day, so I thought I'd share it around as I'd written it up. Ball Speed and Rev Rate are determinants of pin carry. Like lots of things in bowling, more isn't necessarily better, but it may help.
To calculate your rev rate (in revolutions per minute)
You'll need some extra eyes for this.
1. Get a mate and put a couple of bits of white electrical tape above your finger holes.
2. Get your mate to count the revs and clock your shot with a stopwatch for 5-10 shots (after you've warmed up). Write it down! You've probably got a stopwatch in your mobile phone.
3. Take averages of the times and revs and apply this formula:
REV COUNT / TIME(secs) x 60 = RPM
Ball Speed
The attached table "Ball Speed Chart.xls" provides a quick look up for coaches and students of the game to use to calculate their ball speed. Like everything in bowling, it's in British Imperial units (mph), because it saves a lot of translation into metric.
Hope you find this useful.
Cheerio,
Jason
