I concur with the OP, but single rounds will never occur as a grind is required so WGT maximize ball sales.
Personally I seldom play any unlimited round more than once, including the VUS Open. Do I qualify? No. Do I care? No.
Any unlimited grind is meaningless in terms of skill....and demeaning to those who cannot/will not grind away, but those who are willing to grind will succeed.
At best consider it an eclectic golf tournament....play enough and your bad scores will drop off.
I am not sure if comparisons to the US Open and WGT are relevant....this game is so far removed from reality....and that is all it is - a computer game.
