It's ironic that you say, "people use stats in misleading ways all the time, whether intentionally or not" when one of your biggest soap boxes is to use the period of record that is BY FAR Chicago's coldest of the entire climate record as the baseline (and you often make that even colder than numbers indicate). But I just want to know where you are getting this idea that dustings didn't count in the old days lol. I mean there's literally zero proof of that, not to mention as myself and hoosier already pointed out, since records started there have been 0.1" snowfalls. Actually, some of the oldest weatherbooks are fascinating to look at if you ever take a trip to the NWS. They would put detailed narratives of the weather.
