Help choosing augments for a NIN/RNG!

I haven't been on ranger in a month or two, but I remember in the high 50s and 60s, on colibri, my ranged attacks would always be doing identical damage every hit, same with Sidewinder. I went to all parties /nin, so no berserk factor. Always used meat and vshot. If I stood in the sweet spot (as determined on otherwiki distances, seemed right when I used it anyways) every non crit /ra, critical /ra, and WS did identical numbers so I always assumed (at least at those levels) that it was a lot easier to cap off like that. Either the randomize function for ranged attacks isn't much so at all or I was hitting some wall. Hasn't been the case at merit-level birds yet though.

Yeah, Ranged pDIF function has much less variation than Melee pDIF as you can see from the graphs below (also courtesy of VZX):

As you can see, melee pDIF can vary by .5-.9 depending on random generation while ranged pDIF varies by .1 at the max.
