Encoder ticks/revolution change?

[flameout]

We're running a mix of old and new encoders on our bot this year. I recently noticed that two of our encoders were reading significantly lower than the other two, but were reliable (and matched with each other), suggesting that it's not a failure.

Did kit encoders ever had a ticks/revolution value not equal to 360? I didn't have the opportunity to check counts/rev for each wheel before bagging... I don't know if I'll have time at regionals to verify, but I want to be ready to re-tune our drivetrain code if this is the case (and come prepared with the correct ticks/rev count per wheel).

Thank you.
