Have you run that pack against a different pack that has a (much) higher IR? If you run a pack that's at .9 per cell, and then run a pack that's 3 per cell (with all other things being equal...) how much time on the clock does that translate to? Tenths, hundredths, thousandths per lap? How much actual time are we chasing in the low IR hunt?
If you can run a heat with a good handling car, not touch or hit ANYthing, and turn a bunch of laps with an average within a tenth or two for your top ten or twenty (or more) laps... is a good pack going to be a night and day difference?
How much would battery condition affect your gearing? The never-ending discussion on race day seems to be FDR... how much would your gearing change (to get the same lap times) on two identical cars if one was running a good pack and other an old tired pack, if at all? Just trying to make this into a tangible measurement somehow, and not just people being OCD over IR and measurements because it's something you CAN measure.
