I'm never sure how accurately the battery actually reports its health. Mine fluctuates from anywhere between 86-97%. Just checked now and it says 95.5%.
Just for the fun of it I thought I will share the stats of one of the Macs in my family.
It is a rather old Mac but still in heavy use. It had been upgraded with SSD and more RAM down the road + changed the superdrive once. A new battery will be order the coming week
Will find the numbers for my screenless rMBP at some point.
