Speed is in MPH or KPH, would it be better to go by m/s?
The convention in gaming is APM, so they're just using the nomenclature that is already understood.
An AI doesn't need to do this.

I always wondered why they do that, just spam meaningless things like open/close the stats window or click on the background. Some WoW PVPers did it too (like Laintime, I think it was - played a warrior and ran around spamming the character window open/closed an mashing 'weapon swap' even when there was no earthly reason to do so). I figured it was just the result of too much caffeine for 18 hours a day.
This sounds like it's more an equivalent of tennis players' dancing/hopping around, or martial artists doing their ducking/weaving thing?
Similarly, an APM limit wouldn't directly imply that the kind of "gaming" that you're talking about, where a user/agent simply has to have an average APM over a certain period to be in compliance.
I believe the reason they use APM over APS is because 3.4 APS isn't as meaningful as 204 APM.
