It may be bad, but it is too early to tell. Just use it how you would normally do and run it through a couple calibrations over the next couple months. If a problem pops up you will know. Just don't go putting 300 cycles on it in the next couple months and Apple should replace it if it does decide to go south.
Within the last 3 cycles on my battery I have gone from 97% health to 99% and now I sit at 92%. If it drops into the 80's and stays there, or plummets below, that is when I will worry.
