For what it's worth, every inspector we had that year told it was the first time they'd seen someone use it on their robot.

Didn't 1640 use it for doing speed feedback on their shooter some year too?

Yes, 1640 did use it as a tachometer for the ball shooter. That year our programmers were stretched on other things and there was not time for them to get up to speed on quadrature and PIDS. So we attached the throttle motor to the shaft and ran it in to a rc filter. They had an analog voltage from o to 8 volts. What the programming team did from there I don't remember. It worked. Since then the programming team has learned to deal with encoders.
