Opus Magnum (from Zachtronics of SpaceChem/Infinifactory fame)

Yes, if you are into leaderboards it provides three different histograms (with comparisons against other players).

The problem is that one of them is cost (number of part used) which for most puzzles is trivial to optimize close to maximum given an unlimited space of memory (some nudging will be required to keep tracks sort enough). I made a suggestion in the Steam forums to change that one for memory efficiency (which is a much more interesting problem), but I think it’s too late for such a change.
