That's exactly why I decided to control the archers in my test. When they were controlled by AI, they sometimes charged, sometimes they moved to a different firing position, changing the distance. And it seems that distance does have an effect on accuracy.

Those test should really be performed in a MP battle to assure maximal control over the conditions. The other option would be to mod the speed to 0, if possible
