I'll admit, it's been a while since I looked at the spec, but I thought
raw telemetry was 0-255, but that you could also send values to be
inserted into formulas, to produce the "user friendly" values

Certainly I remember looking at those when writinhg telemetry programs
for PCSAT, PCSAT2, and other APRS Satellites.
