Ah, OK, I see the issue there. So that project would indeed have to be based off some kind of runtime, then. That kind of muddies the waters, when the WUs are different sizes. Could their server just say this WU is .1X in size, or .5X in size, so it gets .1(X) or .5(X) credits respectively?

I guess what I'm trying to get at, is surely there is a simple way to do this, isn't there?
