Exactly. Every event there are so many factors that play in to what kind of snow ratios you will see and model output perfecting this is a long way away. Knowing your climate certainly helps, but even that is only a part of the puzzle. In some cold events we see the flip side of this scenario, and we get a lot more snow than is forecast because it's so fluffy. Using all the above factors you mentioned, and especially important is giving a forecast range of amounts, it's all you guys can do and hope for the best lol. Unfortunately in the day when there are so many social media hypesters you guys will always take the flack.
