Hellcatraz Base Game Grind Question

[Lukerobbo]

I was wondering if your keys stay the same if you are to change the stake, so grind it on a lower stake then move the stake up nearer to the end? Thanks

I believe it shows up with an average bet when the keys are filled.

Your keys remain the same but the bonus trigger will calculate your average stake over the grind
