The battery is still used even if you leave your laptop plugged in -- it uses the extra juice when the system is under high load. I have used my 45-month-old MBP plugged in 99% of the time, and coconutBattery shows 97% capacity at 38 cycles.
Deep cycling only helps calibrate the battery charge indicator, but doing so will lower the battery's capacity simply because you're cycling it.
