Average Energy per match

[Stephen Kowski]

I am doing battery capacity fade studies at my work and wondered how their results could be applied to these robotics competitions, but ran into the question of how much energy is actually used per match.

Has anyone ever collected any data on the average energy used by their robot in a given set of matches? This is going to different per robot, per match but I imagine throwing out some extremely outliers I'd think you can find a pretty accurate average value.

My initial thought is that the battery we use currently is relatively poor for the amount of money we spend and the shelf life they retain. To lose 20% capacity in 6 months by only sitting on a shelf makes me wonder about the impedance growth rate associated with these batteries.
