Thank god for PVR!!!. The delay between shots is becoming too much but thankfully I have PVR and I just fast forward until the players looks ready to hit....which sometimes is still another 60 seconds until contact.
Bill is correct, this does filter down to the public. the main reason I stopped playing beer league hockey was guys started to emulate the pros. After every whistle there was a scrum and grown men start acting like they are in an NHL game, pushing, smack talking but never, ever having the balls to drop the gloves to back up thier mouths. After all the bravado, the only things accomplished are adding time to an already late game.
I have started to notice for a while now that this is the same thing in golf. Players started folding their hands around the brim of their hats while lining up putts(ala Tiger) even on cloudy days. Players are now dropping their clubs during a follow through after hitting a bad shot(again like Tiger). 30 handicappers stopping their shot routine to pick up grass to see if the wind has changed. It is amazing how quickly the public picks up on these things. Right after Weir won his Masters, everybody and his uncle up here in Canada started using the same preshot routine, pull the club back and then reset and actually hit the ball. While I can appreciate looking for every advantage by emulating the pros, why dont they start with the obvious, pounds out some seeds on the drving range. Actually use a practice green to hone putting. Dont use the course as time to practice making your 3 footers, do it on the putting green. You wont get better at golf by making that 3' putt for a snowman.
History being the teacher, rounds of golf will only get longer not faster. In all honesty, not really sure it can be fixed. Personally, I just try and be polite and remind my group that we need to pick up the pace.
