That is my max battery capacity I could have sworn it was at 6700

Let me know

its a brand new 13 inch MBAIR.

I don't think it's anything to work about unless it starts dropping. Mine right now says max 6631.
 
It's normal. There's some variability in the prediction of total capacity.

That's a REALLY impressive bat size for such a small enclosure.

For comparison sake, my 2010 13" MBP only has a 5800 mAh bat.

Proper calibration out of the box will bring it up close/closer to it's total capacity. Out of the box the 11" I had was 4387 of 4680. Two full cycles of calibration and it's now at 4668 of 4680.

It does help :)
 
I have an odd problem with my 11", the total battery capacity actually seems to drop after each calibration. I started at 99% of maximum capacity, have now calibrated twice, and am at 97% of max capacity.

For reference, I currently get 4,572 mAh with a design capacity of 4,680 mAh.
 
After 1 full cycle so far... my max estimate says 6780mAh. I'm expecting it to not fluctuate too much from that.
