How do the stat bonuses in the vanilla mod work?

Hi there,

Thanks very much for making this mod! I just had a question about the vanilla version. How do the stat bonuses you get after 3 and 7 missions work? I was assuming that they would get you the benefits of a higher stat, eg if you go from 8 to 9 Guts you get +30 heat threshold, that sort of thing. But this doesn't seem to happen.

Do you at least get the bonus chance to hit from a higher Gunnery?
