I watched those matches, he played alright but not 770 speed and his hands are shaking that it’s amazing that he can actually pocket a ball.
I don’t think he can win a 650 and under tournament
On one hand we could make a case that an inactive player should have a Fargo that declines more quickly. Or that for active players the older games should drop off faster or have even more reduced weight in the system, so it shows "recent speed" more readily.
On the other hand, that could mean that a super player (700 for example) could sit out of tournaments and just practice and gamble for months on end, then enter a 650 and under tournament (because their Fargo hasn't had an update in months and thinks they are inactive). Then they win the tournament and we all complain like crazy.
Damned if ya do, damned if ya don't.
I'd rather have one-time world beaters have a high Fargo well after they play to that level.
