I have the Retina Display model. After 9 cycles and three weeks my
current capacity is showing as slightly higher than the design capacity,
8612 mAh, vs. 8460 mAh. That is probably a fluke of some sort but the
capacity certainly isn't dropping.

That depends. Is it actually causing you any real problems?
