I worked pretty closely on this. Yes and no, we iterated the minibot to the point of ridiculousness. Minibots were certainly both run on high and low batteries throughout the course of testing but we were never specifically interested in the difference between the times of minibots other then to tell which was fastest and why. As such we don't have any of the kind of data that you're looking for. We knew that a fresh battery couldn't possibly be less charged then one that had been off the charger for a while so we always made sure that we used a battery straight off the charger. Does 10 minutes of sitting actually reduce the battery voltage any significant amount? Maybe not, but we were squeezing every bit of power out of those motors to make it up the pole in under a second so we did it anyway.

Hope that kind of answers your question.
Regards, Bryan
