Dr. Mase of Cal Poly has produced an interesting study. I seems to have have one flaw. He used a speed that would send the ball 5-7 FEET past the hole. I don't knoqw anyone that tries to putt the bal 5-7 feet past the hole.
Had he studied at speed that would send the ball 1.5 to 2 fett past the hole, I'll wager the results would favor leaving the flagstick in. I'm going to do just that today.
