Looking at them both together, though, it's okay to use one's own brain and make out that you wouldn't start casting Steady Shot if CS is just 0.5s from coming off cooldown (unless you need the focus for a Barrage coming right after, or something).
In the scenario you put up, in order to be at 100 focus after casting an Aimed Shot, you would have to be at focus cap when the Steady Shot cast preceding it ended, meaning you broke rule 3 already.
Also, you realize that an Aimed Shot cast literally cannot cap your focus, it can only -spend- focus, not generate it. It costs 30 with ToTH, generates 20 if it crits. Do the math.
If CS is coming up and you have so much focus that a Steady would cap you, then you'd AiS into CS since that's 85 out of your ~100 focus spent with little to no delay.
I get the basic sentiment of "both choices are wrong" in some cases. That's where the priority comes in, e.g. you'd rather cap focus than delay CS more than necessary. It just so happens that the Steady Shot choice would be the one to break both, while Aimed would only break one of them (in a severe fashion), by potentially starving you. That's how on-the-fly decision making comes into play. Believe it or not, I cannot make a guide that considers every specific rotational scenario. Or I could, but that'd take a while..
