OP I'm sorry but seriously, if you're playing off of a 7.5 handicap then pacing out the exact yardage to the flag is not going to make any difference compared to using a laser range finder or sprinkler head. Hell, you could probably estimate it by sight and it wouldn't make a difference. Unless you're honestly going to say your 54 yard shot is definitely different than your 57 yard shot or your 52 yard shot. Then you cannot justify holding up the course to pace it out.
The same logic applies to reading the wind and deliberating over aiming for 4 minutes. You just aren't going to be accurate enough to have it end up mattering in the long run. The pros actually do have the capability to land it where they are aiming with great accuracy a great percentage of the time and therefore should read the wind and the break and the yardage. How many times out of 100 can you land the chip pin high and spin it stopped a few ft away? THe pros can do it far, far more than you and therefore should get a very exact yardage.
5 hours for a 4 ball is ridiculous, nobody in their right mind would need that much time to play a round unless they were having to constantly wait.
