Easy there Judge Judy.
Considering how much Wysocki's rating was skyrocketing beforehand and still only 19 yrs old and still improving, I'd say stagnation was suffering. But it really was regression as his last six months with Innova are statistically the highest(
1050) by a decent margin until recently. He started and ended Prodigy with 1042 rating. His peak rating with Prodigy was with the 6 months of Innova residuals still in there and he was still using some Innova discs.
USDGC and Worlds Results:
2012 - 2nd, 2nd - Innova
2013 - 23rd, 5th - Prodigy
2014 - 43rd, 2nd - Prodigy
2015 - 2nd, 2nd - Lat64
2016 - ?, ? Seems to be on a tear with Lat64 so far.
Other notable Prodigy players struggle with regression(some have also left):
Will Schusterick
Cale Leiviska
Paul Ulibarri
Manabu Kajiyama
Phil Arthur
Nikko Locastro
Bradley Williams
Garrett Gurthie
Paige Pierce
