And your point is what? Those figures that Apple posts are under ideal conditions.
My point is that's what one should "expect" from their battery. Normal variances aside, getting to less than 90% battery condition should take over a year with a daily full discharge rate.
Many people are under the incorrect assumption that the battery needs to be fully discharged and then fully recharged each time.
That might be true although I hardly think that matters.
A charge cycle is a complete drain and recharge.
That's stating only half the information. The charge cycle count is cumulative so that a full discharge and then full charge (as you have correctly stated being a single charge cycle) is actually the same as discharging it 10% then charging it that 10%, 10 times. You assume a full discharge which may well be far from the truth. The cycle count will advance irrespective of the system's battery having never gone below 50%.
Having a charge cycle count of 29 in a month is far from atypical. All that says is that someone with a current system uses it on battery between 4 and 7 hours in a day. It is a laptop isn't it and is supposed to be used on battery right? FWIW my 3.5 month old rMBP has a charge cycle count of 88. Some of us do use out MBPs/MBAs in places other than at a desk.
A battery condition of 89% in a month I would consider outside of a typical variance. Whether AppleCare service will do something about it is another matter for the OP to take up with them.
