On the rate counter I used the encoder index and for the counter I used the rising edges of a 1024 count encoder. I measured the output of a drill going 1,500 max. I double checked the speed via a non-contact tachometer and reflective tape while measuring the speed on the RIO.

I chose the counter this time because I was interested in getting my driven distance in encoder ticks for auto mode.
