Thinking a little further on your question, if the difference between "full charge" on a peak detection charger (assuming a reasonable design and Mfg. execution of the design) and C/10 charging is worrying you then you are flying way too close to the limit.

Trying to put it into perspective, the last 20 to 25% of throttle opening on your engine gives an almost indiscernible difference.in RPM.

That is where we are in your battery/charging/capacity discussion from a practical standpoint.
