I'll let the battery math wizards help you "convert" numbers, but since I've owned a couple of Integy packs, here is my experience...
They have been reilable, with no failed cells or other issues, and have held up for a good "lifetime"... However, take it for granted that the simple fact of matching at 20 amps will GEATLY inflate the voltage and runtime numbers, and you just cannot compare them to other matcher's cells.
There is also an issue of "usage".... Cells are best evaluated when they are matched and cycled under conditiions similar to what they will see on the track. Except for stock offroad, almost everything sucks more than 20 amps out of packs today -- cells which test/match perfectly at 20 amps may fail at 30-35 amps. The other matchers have bumped up their criteriea to match the track, and thus they tend to give you not just more realistic numbers, but also less cell failures after you start using the packs...
