Hi Jay, I have tried to measure the effect you are speaking of. It would be rare for it to be as large 2 cents and it is inconsistant from piano to piano even with the same make and model. I suspect if you are having this sort of pitch drop after doing a unison that plate flex (pitch correction) is making the difference.
