    Okay so I bought the newest 2011 macbook air (4GB RAM, 128gb SSD) and downloaded the Cocoa Application which says that my battery is above 100%. Is this normal or is it reporting incorrectly?
    I've had the machine around a month and charged it about 9 times (it says more but there were already charges when I received the machine) (102% since full charge yesterday)

    Plus after a full charge, I left my macbook air closed for 18 hours and 4% had been used. Extrapolating this for days, would mean I guess closer to 20 days than the 30 day standby time advertised. Should I be worried?

    102% is nothing. On coco, I had it once hit 16888% haha

    Something wrong with the battery indicator that came with your air?

    Yes perfectly normal.

    I've seen mine fluctuate from 95% to 101%.

    Not at all. It's perfectly normal for battery health to fluctuate and not be completely accurate.
    No, it's normal.

    This should answer most, if not all, of your battery questions:
