Who-o-o-o-oa, TheNewSharkster! I'm not holding *anyone* back. If someone wants to make a pool cue device with an accelerometer in it and develop a program that will quantitatively analyze a pool stroke, there's nothing I can do to stop them. I'm just voicing my opinion and questioning the need for a such a device.
Yes, *of course*, technological advances in pool have made things better. Without them we wouldn't have leather tips, chalk, rubber rails, consistently machined slate beds to play upon, and plastic pool balls impervious to changes in temperature and humidity. However, I *am* saying that certain technological advances in today's pool cue equipment may not necessarily be all they're cracked up to be because today's pros aren't surpassing the pros of the past with such significance as to claim their success is due to the technology.
I agree that videotaping a golf swing and analyzing it with computers can help a player to significantly fix their swing. There may be a lot of similarities between golf and pool, but a golf swing is quite different than a pool stroke. When you swing a golf club, the head travels many, many feet in its upward and downward arc. As the club head comes down to strike the golf ball, there's a very small margin of error where and how the club head can properly hit the golf ball. Those small margins will magnify into large errors as the golf ball travels down the fairway.
Compared to golf, the distances in pool are tiny. The typical stroke of a pool cue is... what?... 10 inches. When you strike the cue ball, I'm guessing there's a one millimeter margin of error on the cue ball and a one millimeter margin of error on the object ball. Yes, these small margins will magnify down table and result in a miss. But, with the typical pool shot being... what?... 4 feet long, the resulting magnification in error won't be anywhere near as significant as those in golf.
My point is: I think an accelerometer pool cue device with quantitative stroke analysis would not *significantly* help the player fix their stroke, even coupled with lots of practice. Maybe I'm totally wrong. Maybe the device will revolutionize the pool coaching industry.
The fact of the matter is we're just debating whether or not the imagined device would be useful. You think yes. I think no. We could go back and forth all day. Until someone actually builds it, this is just a moot point. We might as well argue over blondes and brunettes.
