Loiter rate... 0.2 too low?

I loiter just great, but it’s sluggish in response to the controls.

Jack the rate up?

I’ll answer part of this one too:

I went from 0.2 to 0.4 loiter rate and it was downright unstable in loiter mode. It almost did several flips of death and I finally got it back down on the ground.
