Taking snow measurements at that elevation seems hard in itself as it does seem logical or possible that wind can transport snow up there like a half mile away. The cam itself may not drift but it's possible some of the snow isn't coming from the sky anyway. When you get off Heavens Gate you stare at a couple hundred feet of higher terrain up to the tower. Sometimes it seems like the west wind fills in that area and even upper Ripcord and Paradise. That'd be my guess as to why there's such a huge difference from top of Bravo to top of Heavens Gate. Heavens Gate top has the benefit of wind loading from the west side like there's a reason a lot of the trees on the ridge and west side don't have any snow on them a lot of the time.
However it leads to the question of if the snow lands there does it matter where it came from? If the top part of Ripcord is 10" and you can ski it, does it matter if 6" fell from the sky and another 4" blew in from a quarter mile away from the top slopes of the west side? At the end of the day you're still skiing through 10" of snow. But the more I ski off Heavens Gate I'm convinced some of it is blow in from the slight rise higher up the ridge. Sort of like Jay Peak's face chutes and the top stuff off the tram.
Anyway that may be explaining the huge ranges in snow totals. Yesterday when you overruled the cam was actually one of the more uniform reports I saw of the season with 2-2-1" instead of the 7-2-1" type spreads the cam can give. Kudos for taking the approach that maybe we need to look at this a bit more and monitor its accuracy.
