What are the signs of separation in a tell tale. I was testing my kamm back and got flat tell-tales that scooted side to side a bit. Do they have to be straight and motionless or is a bit of side to side ok?

What is a good angle to start with for a kamm back. Profiles are nice but my printer ain't that big.
