my late 2011 macbook pro 13" was at 290 cycles at around 16 months its battery health was 90% however when it was only 50 cycles it was at 96% it used to fluctuate back and forth from 98-94% so rest assured its normal on any macbook. However if any issue is there you would get a warning and apple will gladly help you resolve it as and if any issue crops up till then enjoy your macbook.
