My opinion is that he can't, he absolutely can't....and i wouldn't making it an issue if not on eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeevery SD, some 65 average player who noone knows, seen him playing or having match plays and alts under his belt (not to mention not streaming), decides to hit -22, -23, -24!! This is a repetitive pattern, it's not just a random thing which happens once in a year.
Have you ever had a bad SD round? One where nearly everything that can go wrong does?
With all your Experience I would think you have had one of those games as no one I know has never had that happen.
I've seen the opposite as well, someone just blister a scorecard even though everything about their stats/scores says they can't do that, as well as having played them in stroke or MP many times and seen how they shoot.
I get that this is your opinion, it just looks like a weak argument for cheating- and I have no idea why you and paul are getting so emotional over this guy.
