I don't know exactly how live games work but I haven't seen many live games where there is a lot of 300+BB play, and I've played decent stakes live pretty much everywhere, australia, europe, east coast, west coast.
The only time you'd see that is if there was a huge mark sitting that deep and a no max buyin table because the biggest max buyin I've seen with the exception of some few no max buyin games is 250 bb.
100bb deep is standard. That isn't debatable.
I am sitting with 10k
. They don't take that. Guess no match Tehan can come in here and say he only wants my action if I'm 300bb deep or more, and we can move on with our lives.
