I don't really follow what you mean by a good perm Komp. As with any bet a perm is only as good as the matches that you put in it.
Do you mean at what odds and for what number of correct selections within the perm you can profit?
e.g.
trebles from 4 when the odds of each match are 1.4 is never going to work out well as a single line does you no good. To me that's a bad perm
trebles from 4 when the odds are 1.59+ is a good perm in my book as if you get one line up then you make your stake back and anything beyond that just increases the profit.
Is that the sort of thing you mean or are you just looking for absurdities such as 252 1p bets on 5 from 10 correct scores can win you 100k
