Just to be clear, I wasn't questioning the data from the Northern Greens. I have zero reason to doubt any of the data being posted here at least (which is all I look at anyway).
I was just observing that the best situation here for snowfall is a mix of different types of storms. Coastals, SWFEs, inland runners over SNE, and then upslope all contribute in different ways. It's more slanted towards upslope over your way, and more slanted towards synoptic east of here (Sunday River, for example). Randolph is positioned to get bits of all of it.
I can say as someone from the south, one thing that throws people on the ski place measurements is that those measurements are up at 4000'+ and not at the base lodge or condos where most people are spending the bulk of their days. So they hear that Stowe has 60" on the ground and wonder why the outside of their condo only has 15". This issue doesn't occur as much on smaller hills further south where the delta between the base and "peak" at 1,500' is very little, and it's all manmade anyway. I can see why people who visit the NNE resorts once every few years aren't straight on this.
