Yeah in the more blocked flow events the west side areas can pack more fluff in for sure. Personally I also think wind plays a big role as well as ratios… blocked flow can lead to more wind on the east slopes and there are many events where I think total QPF is the same but west slope spots are dead calm with larger flake growth and the east side is wind-packed smaller flakes. That leads to more inches west but the same snowpack water on both sides.
You could spread 1.0” QPF across the Green Mountain Spine and see snowfall vary from 10-20” just based on wind and flake size. Gusty winds, shattered dendrites and ground packing, vs Champagne Powder fluffing up nicely in a calm environment.
