You are going to wear your packs out before you race them!
I never cycle stuff anymore. I just keep track of how many MaH are going in and when I see a drop in capacity or if they go soft late in a run I sell them to the stock guys.
Most 3800's take over 4300Mah during charging.
Most matchers that know thier stuff put 500 sec of charge at 6A into newly matched IB packs before they get shipped out. This keeps the cells alive on the shelf due to IB's high self discharge rate.
