Airspeed Error Reading on Powering Up

I’ve made 5 Preflight_Calibration and MP shows ARSPD_OFFSET between 34 and 39.

Yeah those aren’t unreasonable offsets for that sensor at all. Without looking at a log it’s hard to give any more comments on it, but with that level of swing in a room that shouldn’t have much airflow I’d probably not fly the sensor, as that looks very wrong.
