Minimum Flywheel Encoder CPR

My team was considering buying cheap 20 CPR encoders for our shooter, reasoning that the encoder on a high-speed flywheel can get away with having less resolution without hurting performance. All the other encoders we have worked with have had 4092 CPR (or 512 CPR on a quadrature), so 20 CPR encoders seemed kinda sketchy to me.

What is a good rule of thumb for minimum CPR for a flywheel of a specific maximum velocity?
