I'm using 5% mutation rate and have 1 elite clone. I thought that meant that the whole population would be based on the winner with a 5% mutation chance (so all 19 are children of the winner). However, I have a track with an "impossible" hill and every round there's one car that almost makes it over but it's never that one which is blue next round.

How does this work exactly?

EDIT: It seems the one that almost made it was a replay ghost or something and not part of the population. Still wondering if I understood it correct though.
