can you explain what you mean by 1/20 of villain's chips?
Set mining depends on effective stacks. You'll hit your set 1 in 8 times, so effective stacks should at least be 8x the bet as a minimum to be able to set mine.
However, in order to be profitable, effective stacks should be deeper, at least 20-25x the bet. These extra bets act as a buffer for situations where you hit a set and a) don't get paid off or b) still lose.
