Percentile change of the April 2017 subject test

I took the subject test in April and when I checked my score in August, I found that my percentile dropped 2% compared to the percentile I checked in May. However, the scaled score has not changed.

Since there is no subject test between April and August and hence no need to rescale the percentile, why does my percentile change?

It probably changed because of the new system. Apparently there won't be any penalty because of wrong questions. And there moght be other changed I am not sware of. That's my guess, of course. I would ask if I was you. If you find out, let us know.. or maybe it's posted somewhere in the ETS website.
