A little bit of both. I'm pretty confident in my distances since I've been using ShotScope all year, but if ShotScope has me at 160 for my 8-iron I've been pulling that club at 160-165 (ego) So for example, the par-3 #2 I played had 155 to the middle with pin in front so I figured I need to hit 150. Rather than rounding up and using 9-iron (per ShotScope 148 P-Ave) I clubbed up to my 8-iron (P-Ave 158). Low and behold, a 152 yard 8-iron finds the green.I guess my question is "one more club than what"? Have you been basing your club selection on incorrect information about how far each club goes?
Or maybe I should ask, what were you basing your "ego" distances on?
