54/55 is a fantastic score!
The reasoning behind my original claim of the elite players will destroy this course is this...
I play with the free Starter ball. And I was able to shoot a 60. That is why I thought those using much better balls would be able to shoot really low.
That is good reasoning.
When you look at extreme low scores though, you need to look at what is possible without adding in the "luck" factor. In any conditions, hitting all greens and all putts would be 54. If you have favorable winds on 6, 53 is the number. And if you have a tail wind on 18 along with the "favorable wind" on 6, then there is 52.
I have played quite a few times now, and I have only had one wind that would have allowed me to hit 18 (sadly I wasn't carrying my 250y 3w at the time). I have made 1 eagle on 18, but that came from holing out.
As for #6, I get the wind against me over half of the time and have no chance of reaching it. I would guess close to 60% of the time the winds have been against me on 6.
There have literally been thousands of attempts at this course. Hundreds of those attempts and possibly a thousand + have come from players capable of going real low. And when you look at the leaderboard and see all the names of great players that are not on it yet, I assure you it is not because most of them haven't tried yet. Out of all those thousands of rounds, only 3 players have broke 54.
53/54 is destroying this course. Any number lower requires the combination of skill and luck.
At Erin Hills in the VUSO, only 15 players broke 54 and only 2 players broke 53. Not only that, but I remember at least one of the par 5s (#1) was playing from shorter tees. It was easier to reach then Torrey Pines #6 (and with it being #1, you could hit restart until you reached). I can't remember if any of the other 5s were within reach.
I think this VUSO will play similar to the way Erin Hills did, but with less scores under 54. There 56 made the cut, but not by much. There were 145 better scores.
