Did you do the battery mod (aka pulse charging)? Looking at the graph, it looks like there was a lot of quick charge/discharge cycles. Pulse charging will force more juice into the battery due to the charger starting at a higher output for the first second when it it first plugged in until it settles to the correct output. If i remember right, this is due to the capacitors in the charger ramping up to being at full operating voltage from 0. Usually this only takes a fraction of a second and is only done once when the charger is first plugged in, however some clever person discovered if you can leave the charger plugged in and turn on and off the power to it quickly (this is where the pulse name comes from) it will continuously be in that higher output mode and force more juice into the battery. Those that have reported being successful in doing this have done so by doing things like plugging the charger into an outlet that in controlled by a light switch and switching it on and off quickly for a length of time. You have to be careful though, the batteries have been known to catch fire when pulse charged since they were never designed for it.
