Hmmm so you recorded 2400 rolls and then manually added them up (in sets of 1200) to get the two averages? That's...a lot of data to do math on, whether you did it by hand or used a calculator. Transcription & math errors might have a significant effect: accidentally entering "155" instead of "15" once will will shift your average by ~0.1. Those uncertainties still *probably* wouldn't explain the 3.5 difference you found between player and enemy, but...

Not quite. It's half the die's value plus 0.5.
