Michael Whitaker,
If you're trying to tell me that play, and tournament play is faster today than 50 years ago, before all of these "assistants" were available, you too are dreaming
When's the last time a foursome or a threesome played in under 3 hours ?
A foursome in 3.5 ?
Is competing in, and winning a tournament more important today than it was 50 years ago ?
NO, it's not, but play has slowed to a crawl.
When I was competing, especially in qualifiers, I always requested the last tee off time.
Why. ? Because I knew I'd be out there all day, and with the last time of the day, I could practice my putting to my heart's content, rather than standing around and stewing about 5+ hour rounds
I've also officiated local, NJ, MGA and USGA events, so my data base, experience wise, is fairly extensive.
