Just wondering how many cycles per day you are averaging. I've got a 2.4 13" that i've had since June 1st. it has 40 cycles. That's 72 days, so averaging just over 1 cycle every two days. Light to moderate use during this time.
Because the way Charge Cycles are counted (total battery use from 100% to 0% or any smaller parts, like 2 x 100% to 50% which add up to even 100%) it is totally useless to count days for how long one has had the unit because it is completely depending on use. One person could use on battery for 1 hour a day and another 10 hours a day, or anything between that...
I have tracked my Charge Cycles increases by tracking my actual percentage how much I have really used the battery. I don't even try to estimate anything, as it is pointless if your try to do this by "feeling".
With my unit so far Charge Cycle counter has been increasing by 1 every 1 to 3 days (depending on how much I used it on battery at the time).
I've been measuring my actual battery use, and so far counter seems to increase about every 80% or less actual battery use. So if no one is actually counting their real use, it is impossible to say how much they really get real use per charge cycle.
You mentioned your CC count and days, and that light to moderate use, but can you say exactly how many hours total use on battery and how many percentage of battery you have used in that time? I bet you don't.
