I think the three mins looking for a ball has made it worse.I would guess that, in a 3 ball, an extra couple of shots a hole that are short putts might add 5 minutes to a round and any searches will likely go the full 3 minutes before giving up rather than a minute/chuck another one down but thats unlikely to add more than 5.
That 10 minutes is hard to pinpoint as "extra time" over the round of 4 hours.....
We're not seeing rounds extended because of WHS..it's more to do with clowns not letting groups through and generally being slow anyway
If you start looking and don’t see it right away ,I have heard players say “they can wait another two minutes,that’s not long enough to let them through”
But with five minutes to look players were more likely to allow games through while they looked.
Putting handicaps up has a impact imo.
Anyone who needs 54 shots needs to learn to hit the ball first before going out in comps etc.
It’s about money now!
In the past clubs would not let you join unless you could play to a certain standard “ snobby or sensible” take your pick.
But now if you have the cash your in!
