I like that US Digital doesn't take the decoder into account. Their encoders don't come with decoders, so why should it be their job to decide things for you? They do provide both CPR and PPR if you want to calculate your counts per revolution given your own decoder.

Yes but factually the other guys are often doing no less. They are sometimes using different terms to do it. Course this means you may have to double check.

FRC11 has been using the Grayhill potentiometer style encoders recently. Too many issues with the end of shaft style. Using the terms used as criteria for this topic we get 128 cycles per revolution.

Depends where in the gearbox/ system. You don't want to flood the Roborio with data.

EDIT: On topic: The results of the poll are pretty interesting. It looks like most people are using 256 or 512 CPR encoders, with a few people using 64 CPR (or just picked the wrong option in the poll... I should have used CPR instead).

The two common encoders are 250 & 360 from US Digital. Not sure about the (much higher) others.
