Did I claim 84 people are cheating? No. -15 under wow. Incredible. Notice no one got -16? You cannot get a -17 under and only get 3300 pts. It's not possible.
only thing i can think would be he drives the green every time and putts. Guy below him does chip ins, rising shots, spiral shots, there are ways to get extra points but that much of a spread seems farfetched
We were talking in depth about erratic ball flight and how even with PI the ball can go off the heel or the toe of the club if you use backspin. Apparently they decided they wanted to nerf backspin with this game so they added a feature to just randomly screw you. It's in that topic he talked about this score.
