The last thing I did in-game was to move up my “10-in-a-row” mark for Frenzy: 10 138s in a row, no fishing, no fails.
Best: 10:45
Worst: 14:18
Average: 12:15
5 tiers below whatever my peak clear is really does seem to be the sweet spot. My peak is 143 and I did 10 138s. Back before Frenzy got buffed, my peak was 138 and I did 10 133s.
