Here are some models I created for set mining.
I did two series of models, one where effective stacks are 100bb deep and one where effective stacks are 50bb deep so you can see how your chip stack actually impacts whether or not setmining is profitable. I also used a preflop raise of 7bb which is more standard for live 1/2nl games where raises are usually around $15
this should give you an idea on profitability and give you a better perspective of just what set mining is and what is required...
NOTE: on some of the charts on the bottom, I make the mistake of saying 3bb when it should say 7bb
