I go overall feel which includes pack, cold, favorable pattern sustainability (cold and dry better than warm and wet), amount of legit threats to track, and winter being winter during DJF and not rogue events in Nov and April that just ‘pad the stats’. For example, a winter that ends with 50” featuring alot of nickel and dimes with constant snowpack, definitely during Christmas, for longer periods of time and sustained cold (making it feel like a long winter) with weekly threats to track...would beat out a winter of 65” featuring 5 storms that started in mid Nov spread out to April with constant torches and cutters vaporizing packs in between with brown grass and 60s on Christmas.
