Reasonable winrate for split-pot games (Stud8)

[TS Clark]

Forgive me if this question has been answered before.

Given the split pot nature of the game, as well as other factors, what is a reasonable winrate (PT BB/100) for someone playing Stud8, say at a 2-4 limit? How about for 10-20? Assume the site to be Stars, if that makes a difference, given the varying ante structures at different sites.

Thanks for any help in advance.
