I'd guess that as the pack balances better this will level off - but no sign yet.
Please note that the fabled 66.14Ah is just a magic number, not actual capacity of the battery, but rather something that gets programmed into the BMS as a starting point. Initial change can be fast, due to BMS learning the *real* capacity of the pack. Once that is found, degradation follows its normal course.
