On further reflections...
I would say the statement "scoring 52 is not a realistic score" is absolutely true for approximately 99.99999% of the people on WGT and this is possibly being generous....
If there are 15,000,000 subscribers on WGT and we take the top fraction of 1% say .00001 of those players who have gone on to become elite esports professionals we have around say 150 members that can on any given day post a 52 within say 10 attempts.
Yet, even among that 150, there may be a smaller subset that stands above their peers on a consistent basis... hence the observance of familiar names on the leaderboards.
There may be another group of members within .00002 or .00003% than could still accomplish that feat in say 20 to 30 attempts at the most or less with ideal wind conditions on eagle holes, but they all have years of experience and thousands of rounds under their belt.
So, if your still reading @skbob, take notes, learn from the best and put in the work and maybe in a few thousand rounds and years of experience... a few of us may, just may catch up... either way, the game can be enjoyed in a variety of ways. : )
