My collectability seems REALLY low.

I'm watching this guy fishing for mayashells with stats quite a bit lower than mine

Mayashell fishing

His gathering is 2950ish (im 3280) and perc 2480 (I'm at 2700).
My catches are 500-700..... this guy is consistently getting 800 though.
My mining and bota are perfect, but my fishing just feels.... off. It always seems lower than any guide I watch, despite higher stats.
