Has twist even been considered a factor in getting monos to expand?

When I started shooting the 40gr vmax in a 1x7 twist AR vs 1-12 twist things seemed more explosive. I know SW also changed the twist on the M&P in the .40 because a faster twist kept bullet deflected less in the FBI protocols than the slower twist. In particular they tracked straighter through the angled windshield and steel panel test.
