You say you understand the point but you seem to have entirely missed it, the same problem remains.

The point of the APM limit is presumably to fairly emulate a human player, but the APMs for humans are obviously averaged over a minute.

However, for certain things humans can initiate actions in SC2 in quick succession that, if sustained over a greater time period, would yield a ridiculous APM rate. Think a Terran player highlighting the barracks and tapping "A" really fast, say with a 10ms delay, that would result in 600 APM.

Let's say a human can build 5 marines like that in quick succession. You're going to have to allow for temporary spikes in APM to not unfairly give the human player an advantage.

But if you do that the computer is able to really rapidly execute more complex actions that the human can't because he's limited by the SC2 UI, whereas every action via the API is equally difficult for the computer. E.g. moving 3 different subgroups of marines out of the way of a High Templar Storm. I doubt any human player could select 3 different subgroups of marines from one big group and move them out of the way in 3 different directions within the span of 60ms (10ms for each action of select/move for 3x groups).

So any "fair" APM limit really needs to be dynamic in some way, or at least take into account the complexity of actions (say highlighting a group v.s. tapping "A"). It's not at all obvious how to do this while retaining fairness and not giving either the human or the computer an unfair advantage.

This is wrong. I don't know the exact number, but APM is averaged over around a second. I suspect this is done because APM is a more meaningful compared to APS, for humans at least.

Here is a graph from Scelight that high lights this: https://goo.gl/photos/9cjNxDwWoB1pmWkg9

You still end up with a computer that can perform 3 actions all within the first millisecond of a second and still end up with human-like 180 APM (3 APS), even though no human could replicate what it just did.

How is that any different than someone who goes 100MPH and then 20MPH and claims to have not violated a 65MPH rule because the average speed was 60MPH for the trip?

The units of the measurement do not dictate how the measurement is made.

Because when the cops measure your speed they can do so in an arbitrarily small time period of their choosing, and inertia and power requirements mean you can't be going 1000 MPH one milliseconds and 10 MPH the next.

You could decide to measure APM by saying that the time difference between any two actions extrapolated to sustaining that rate over a minute or seconds couldn't exceed the APM or APS, but as I've explained such a measurement would unfairly give the human player an advantage because humans are capable of bursts they couldn't sustain over longer periods.
