Oh, it's pretty simple actually. Instead of simple orbiting, I'm moving in a straight line towards the point where I'd end up in a precise MEA calculation.

My main worry is it seems like a ton of extra calculations per tick, but in practice it doesn't seem to slow me down that much. I guess some combination of the "don't calculate second wave when you don't need to" optimization, and that I don't recalculate the destination for the direction I'm heading in on the first wave.
