Battery health question

[espressoroast]

Hi all, this seemed strange to me so I though I should ask;
istat pro reads my girlfriend's one year old Macbook (black) battery health as %100 with 65 cycles.
My 2 month old Macbook Pro is at %97 with 22 cycles.

Is this normal? am I just unlucky or can a calibration might solve it?

The calculaton for the "health" of your battery has a bit of magic in it, you are within spec!

I'm glad to hear that, my 6 day old MBP is 98% after 6 cycles, had me a bit worried... lol
