Some quick measurements with my tuner yielded the following results for the high E string on E9th. When the string is taken up to F#, back to E (measure pitch1), down to Eb, back up to E (measure pitch2), the maximum hysteresis was 2.5 cents. Not that I care, cause it never bothered my playing but this is better than any other guitar I have owned.

Cabinet drop:

3 cents on high E string when P1 depressed
2 cents on high G# when P1 depressed
3 cents on low E when P1 depressed
3 cents on high G# when P3 depressed.
