Earlier quoted context omitted.
Why are you looking at the outliers? So by your logic, if a few companies have useless ranges, it makes the whole thing useless? How about job postings with relatively decent ranges like this backend engineer role in OpenAI: https://openai.com/careers/backend-engineer-evals-understand... with a range of $245,000 – $310,000?
You're right, I shouldn't let a few "bad apples" ruin the whole batch. It would be great if the law could say something like "range must be +/- %25 of the target salary" (Obviously that's very difficult...)
"range may have relative error of no more than 10%"?
where the relative error is the usual 2*(max-min)/(max+min)
