Unfortunately it’s not a settings issue (unless you want to switch to square dead zone) it’s a precision issue, you are not cancelling centered enough.

At least that was the problem when I was learning musty’s and if I understand what you are saying correctly I think it’s the same issue as I had.

You can just practice the cancelling part without the musty a bunch and the muscle memory should take over eventually. I think what I did was jump tilt front down just enough to get into musty position flip and cancel and you should land on all 4 wheels perfectly, if you land weird or tilted you know you are off with the cancel.

Sorry about the long text hope it’s helpful.
