What is bolded there is definitely true. I don't agree with the good pattern stuff because I think what most of New England thinks as a good pattern will redeem higher results in the lower average snowfall areas. Our snowfall can be more steady in all patterns, IMO. Of course we have our times when all of New England is raking and we rake really high too, but it's all relative to average in my mind. Average sets expectations.
In a below normal satisfaction winter, we'll certainly seem to do much better. Crappy winters are usually warmer or more cutter-ish, but even at +7 this month, our average highs were below freezing. Warmer winters also have the baroclinic zone closer to us, more activity, etc. It's been a below average winter up here, but we've had a winter with consistent snow cover and some snowy weeks.
