Will this affect the current high scores at all? I mean if I score lower than my current highest will it be discarded or will the higher score get overwritten by my latest attempt which was lower?
The highest score is kept, it seems. The only weirdity I've seen is if a user scores the same exact score more than once, both scores may appear in the top 10.
There was a request, that if two people tie, the higher placed winner is determined by the shortest time playing, but I'm still looking at how that might be accomplished.
