One thing I am trying to accomplish in improving as a bowler, despite being only a part-time bowler for now, is to educate myself in the game more than I did when I was younger. So I am paying attention to the finer things in
PBA tour telecasts, league bowlers, and my own game.
Rev rate, expressed in revolutions per minute (RPM), is one area in which I'm paying more attention to lately. Not only am I seeking my own ideal rev rate, but I am also paying attention to what rev rates are required to succeed at the highest level. Ball speed is another area I'm paying attention to.
Some sample
PBA players and their ball speeds and rev rates, from the Winter 2009-10 issue of
USBowler:
Rhino Page - 17/18 MPH, 310 RPM
Tom
Smallwood - 15 MPH, 350 RPM
Bill O'Neill - 17/18 MPH, 450 RPM
Wes
Malott - 18/19 MPH (but looks like he's hardly trying; he's one strong dude), 400+ RPM
These were general estimated averages, which is about all I can come up with for myself without some high tech equipment. In a meeting at work this week, I scribbled out some estimates. (Don't worry; it was a meeting I was required to be in, but in which different groups reported on their status. My part lasted five minutes.) It's a good thing I remembered my algebra. I guess my teachers were right when they said some day I might use this stuff at work.
To figure out my RPM I need to use what little info there was available to me. The bowling center has a feature in which your ball speed is calculated. My shots averaged 15.5 to 17.5 MPH. Part of the wide range is because of my own inconsistency, but much of it is also in experimenting with the lanes and shot as I try to find the optimal way to the 1-3 pocket. My average and ideal speed did indeed seem to be right about in the middle at about 16.5 MPH.
So as with my golf game, my ball speed is not among the big boys, but somewhere in the mix of the elite. That's encouraging.
Back to RPM. My best guess as to how many revolutions my ball performs before hitting the pins is 12-13.
With that knowledge, and my ball speed, I can figure out rev rate.
Thus rev rate = revolutions per minute
= revolutions per mile x speed in miles per hour / 60 (to convert hours to minutes)
= 5280(feet in a mile)/60(feet in lane length) x 13 revs x 16.5 / 60
= 314.6 RPM
Plugging in different numbers to cover the range of ball speed (15.5 to 17.5) and revs (12 to 13) give me a possible range of 272.8 to 333.7.
This has
PBA potential, but it probably wouldn't hurt to up the rev rate another 25 or so RPM. Typically, the only lower-rev players who've made it big on tour are lefties, like Rhino Page. (Why that is the case for lefties can mushroom into sometimes heated discussions.)
The most successful
PBA player in history is the right-handed Walter Ray Williams, Jr., whose rev rate is around 300 RPM (my best guess). But Walter is the exception that proves the rule. They call him "Dead Eye" on tour, because of how ridiculously accurate he is. Nelson Burton, Jr. used to always say direction is 95% of the game, and Walter's success seems to back that up.
How accurate is he? Consider this: Williams is a six-time world horseshoe pitching champion.
