Yeah, the numbers are weird. I'm in SF, full-stack, with 20+ years of experience (and leading several successful exits), but I can't seem to get a job making as much as a mid-career developer (according to that calculator).
To be fair though, I don't have time or patience for long interview processes. But, on the other hand, a lot of times I get rejected just after the phone screen (with no feedback, of course).
