Well PDII was a 6 hr measurement. I have heard from those in E BOS that they felt it was close to that amount. But the blizz of 78 probably would be higher if they had the same measurement technique. Also, it's possible the blizz of 2005 could have been close to that, but they measured on a freaking cat walk for that, I was told. LOL. As usual, snow measuring has a high bar of error...and many do not know what they are doing.
