The games I play in have avg stack of $300-$800, then they tend to leave once they reach $1,000+. You can change tables without bringing your entire stack, which is actually enforced by the casino, they don't let you bring your whole stack unless you come from a broken table.
If you are playing 200bb+ deep i.e $1,000 in a $3/$5 game. How much will your hourly improve given you are a good player at this stack depth compared to 100bb ($500) deep?
I would guess maybe only 1-2bb from like 7 to 9bb, but I am just guessing. If you have experience in both games please share your results or thoughts on the matter.
Maybe some one can filter PT4 for online results of deep tables vs 100bb deep?
