I remember seeing a video on this phenomenon somewhere on YouTube, but no matter your SMV, if you're the highest in your group, you get a boost--even if you're like a 7 among 6s. It's hard to compete in that situation.
As as far as I can reckon, the only way around this is talking to your friend and asking him to actively wing for you. To have him boost you and maybe even disqualify himself to the girl you're interested in. If he won't help you, I'm not sure there's much you can do to compete other than treating him like a standard AMOG, which is probably problematic.
