Battery Health on Macbooks

So, there was this discussion a couple weeks ago about the battery health on the MBP line, and i had this weird experience of fluctuating battery health on my rMBP, i thought maybe it was because i had gone through 2-300 cycles on the thing, so i decided to test it out on a relatively newer battery on a 13" MBP, and this is what saw over a period of days.

The fluctuation of battery health is quite jarring, there is a drop of more than 700mAH at one point. So it proved that it wasn't just my mac that did this, my question is, why does it do this?

UPDATE: I've let it run for a few more cycles, and the pattern repeats itself. I find it incredibly interesting that it would do this in such a short period of time.

Is there an "electrical chemistry" familiarist who can explain these mysteries of life?
