I get the point on the bending, and agree about the gun butt sticking out toward back under shirt while doing that, but save that one movement, anything on the point of my hip (IWB or OWB) sticks out far enough to look like a hip deformation. Or a gun, if you're hip to noticing.
I'm still quite careful about printing and find for my still too rotund middle, about 4-4:30 is overall way the best -- though I never went so far as to video, certainly have done extensive mirror tests. Then again, I've only IWB'd three guns, all with short butts. The difference between my XD subbie and XD service is dramatic, I don't even use a Pearce pinkie extension on the subbie, as I object to even that extra length to the butt.
I also carry the rig low in the waistband, and have only used holsters with clips off the main body of the already widest part of the rig. Have found that anything higher prints worse too.
