Finding RPMs with encoder

That's my understanding of the WPILib code. But I'm not a WPILib guru.

Also, I have been told that 4x deciding is needlessly complicated for what I am doing (maintain RPM on a shooter with a PID) would you agree with that and if so what do you recommend?

To answer that, I need more information.

What make and model encoder are you planning to use?

Where do you intend to mount the encoder?

How fast will the encoder be spinning at your shooter operating point?

Is the motor output shaft directly connected to the wheel? If not, describe the transmission.

What motor and motor controller are you planning to use?

Will you be connecting the encoder to the RIO, or to the motor controller (if SRX)?
