My setup was obviously measuring time between ticks, and I was spitting out the reading every 100ms.
I agree that a 10Hz sample rate doesn't indicate which way it works. My friend bought their dyno several years ago and was able to determine that it was counting ticks instead of time between ticks. He wrote the company to convince them that the data was pretty bad because of this mode of measurement. They weren't willing to work with him on a fix at that time.
