I've owned my mid-2010 macbook pro for about 7 months now. It was manufactured 10 months ago. My MBP has never been 100% or even 99% capacity. I'm really anal and paranoid about these kinds of things, so of course it's bugging me. I've gotten used to it, and i'm whatever about it. But I recently checked and it's 95% now? with 23 cycles? I calibrate my macbook once per month.
These two statements seem to contradict each other.
But to answer your question, it seems fine to me. The battery in my own MacBook seems to fluctuate quite a bit, higher on some days than on others. Unless you're noticing a performance issue, I wouldn't worry about it.
