Beta4: Really high PIDP.SRate vs prev. flight

After finishing autotune, while in stabilize mode, PIDP.SRate averaged 12 and the aircraft flew fine. On the next flight, the PIDP.SRate average was 117, and was constantly getting clamped down by PIDPDmod! I don’t remember changing any settings or hardware between flights.

First flight, which includes a complete autotune session:

Second flight, with high a PIDP.SRate:

There seems to be a bug where the pitch P value gets a little more than doubled on the next power up.
