I'm not sure the calculation would be a simple one, or even possible beyond very rough guesses. The problem is that depending on the way the match is played, your current draw can vary significantly, thus affecting battery life.

For example, I inadvertently left a robot idling overnight and it was still on, but the battery was down to about 6V. This was almost a 10 hour period. I would hazard a guess and say that the immediate battery voltage reading is "good enough."
