Obviously there is so much more to the equation than a STEP1 score. People often match with scores in the 220s and 230s. I don't know anybody personally but I can guarantee people have matched with scores in the 200s and 210s (these people don't tend to share their scores) with other shining qualities.
It's all about the overall package. I can tell you that with a low 230s, I managed to get 35+ interview invitations. I have friends who had scores in the 220s and still interviewed at places like MEEI, Iowa, Duke, Wisconsin and other highly regarded programs so take that for what it's worth.
