It helps when you post about stuff like this to provide references, like for example a link to the scoresheets in question (which make analysis of a situation much quicker!), but I thought about it for a while and realized that what you're referring to here is probably a bit of a dilemma with respect to scoresheets in particular, in that they don't report your alert outside Complex 0b10 (because it doesn't actually impact any gameplay elements on those maps themselves), but technically they can impact later maps because you're accumulating some amount of alert that will matter later, so you do still get high alert bonuses by continuing to fight under those circumstances.
One alternative approach I've considered here would be to make alert gains in non-0b10 areas work like spotters in Recycling, applying alert directly to later applicable maps rather than recording it immediately. This would remove the inherent disconnect that you see between those two factors (high alert points could still be earned later if the fighting continues in the future 0b10 map, just not immediately). At the same time this makes the general alert mechanics even more opaque by creating another kind of disconnect, so this, too, presents its own dilemma...
I don't really like the idea of delaying alert like that for a number of reasons, though it also doesn't make a lot of sense to leave the bonus even if you are causing that much destruction, if only because by later transitioning to other maps you'll be shedding a fair amount of alert anyway.
So maybe in the end the best option would be to simply remove the alert-based bonus there if driving up the alert doesn't have a correspondingly strong enough effect. It's at least the simplest option so I guess that'd be the one to do for now unless there's a compelling reason to add the other (which seems like it would have some nifty potential, but also be more confusing and complicate the design).
