Yeah the plotted values I posted are human obs. Dryslot posted the satellite derived ones that estimate depth via water content. Human obs of depth and s.w.e. are factored in, but I’m not sure how many data points there are. It’s possible for me to have say 20” and Tip has 14”, but Tip could have more water content due to rain, melt, wet snows, etc. If it’s using the same ratio for both of us it would see my pack as being less than his.
I think this has gotten a lot better though since cocorahs became popular.
