Brilliant video Jack.
I think the size of the piece of meat you are dry aging is important. I.e. the typical supermarket cut of steak is likely way too thin. Sorry if I'm saying something way too obvious.
This is proven out by his 100 day dry aged picanha video. By the time he finishes trimming, there's not much left and it tastes pretty funky. Probably would have been fine with a much shorter duration.
Either way, the smaller the piece, the less you should dry age.
