The Vegas Matt channel posts a running tally in the video descriptions. YTD is just inside of -$200k, currently halfway through.

I watch some of the videos, but I'm not an obsessed fan. I take time out to play with my cats: Matt and EJ.
I'll have to be more alert, but I would say they hide their acumen well. Sometimes they'll speculate as to whether a particular slot has true or perceived persistence, but they never talk about edges. That's probably good for their popularity as everyone hates APs.
