One Best Delivery Speed for Touch

The physics of ball-hole interaction in putting teaches that there is really only a narrow range of optimal delivery speeds for instinctive putting and optimal capture. An examination of the way a ball drops into a hole, or fails to drop, demonstrates that around 2 revolutions per second satisfies the constraints of getting the ball all the way to the hole without going too far past while arriving with a speed that correlates to a generous effective hole width. Touch is not really personal or individual, but a matter of straight-forward physics that applies to all golfers. And only the golfers who successfully adapt to the requirements of reality will, in the end, be great players. This recent post of a video on the PuttingZone YouTube Channel explains the details:

PuttingZone Book Available

Finally, the PuttingZone book, Geoff Mangum's PuttingZone: Science, the Brain, and the Mechanics of Instinct for Putting -- A Professional Guide, is available as a PDF eBook. This book will also be published later in December 2007 as a limited first edition hardcover, signed and numbered in a first run of 1,000 copies, from Hornberger Druck GmbH in Maulburg Germany.

If you are interested in pre-ordering the hardcover limited first edition, the advance price is $34.95 US and Canada or $39.95 International (includes S&H).
