AFAIS, the real USO will play #1 sometimes as 598 yds Par 5, but only 496 as a Par 4, in swing with #18 for a combined Par 9 rating.
Similar to last year at PIN, when WGT took the length of #4 from the 1999 USO (Par 5) and combined it with the new layout as a Par 4, "forgetting" that it would play much shorter during the 2014 competition.
These details mark an unfortunate change against the former habit to painstakingly reflect the USO conditions, as seen @ BPB #1, #7, #15.
Even at OLY, the numbers appear to be correct. I've seen 520 yds for the real #1 (533 here), and there's a perfect match of real and virtual setting for #16 at 650 yds. Only at OLY #2, the scorecard lengths don't match with the virtual display, not even reaching the green from the short tees.
Icon confirmed last year that there will be no correction to PIN #4, and I don't expect any change now.
I conceed that it's particularly difficult here with the variable setting, and a reaction to the extremely low scores may have a reason, but some of the "realism" feeling is lost.
After all, it's a game, and I like CHA despite the beatings it provides to me.
