Relating back to the "formula" thread, this shows why many go conservative to ultra-conservative in design and set up, to avoid being criticized. No one really knows where to draw that line, because no one can really predict the weather.
My take is, however, that there ought to be, under reasonably presumable conditions, at least one way to play at any hole location and make par, even for the top players. (A fade, draw, or some other shot pattern might be required, and that might take some or much of the field out of that par possibility from time to time.) Obviously, there can be too hot or near hurricane days once in a while. Not sure how to test that line, but if play is cancelled or suspended for wind, or to water certain greens every hour, more than once every decade, the line may have been crossed. Are every 5 years too often to have unusual playing conditions? I don't know, but probably borderline from the host USGA's POV.
For what it's worth, of all the last generation Tour Pros I know every one of them said that for the Masters or Open, they may have thought the conditions were unfair, but because of what the tournament was, they were going to play it and not complain, whereas they might if it was a PGA Tour event (including the TPC Championship and PGA Championship) where they felt they should have a say. (because they might not be invited back to the Masters)
To me, the saddest thing was 7 at Shinney turned from being played as a Redan into trying to cut the shot into the bank to hold the green. However, I still view that change in strategy as inevitable for even normal green speed Redans. It's the player's job to negotiate the hole, even if the gca has tried to ask him to play it a certain way.
I have no problem even with the traditional Open setups. As Tatum said, they are trying to separate the field into 1 and 143. Or maybe 4 and 140. The normal PGA Tour stop is trying to keep everyone competitive (and you can say it's more exciting that way most weeks) and out of embarrassing score territory to avoid hurt feelings (i.e., protect the lower half of the field from embarrassment)
Summary? It is what it is. I know the powers that be take it all very seriously and talk endlessly about every possibility, whereas back when I was setting cups as a summer job at a muni, I never gave borderline cup placements a second thought....and I was the only golfer on the crew, which is why they gave me that job, LOL.
