Yesterday afternoon, during the Belgium-US World Cup match, the leaderboard showed some player named YOYO posting five perfect 15k Countdowns sandwiched around a 14,939. Never noticed this handle before so I looked him up this morning:

It also doesn't appear that he played during the same stretch on the previous Tuesday so maybe he wasn't seeing repeats.
Maybe he just got real good?
