I must have found a different person, sorry. Can you please email ernst@gitlab.com with your case? If the calculator is so far off we would love to add that data point. The most heard criticism seems to be that for low rent parts of the US the calculator is too low. Before our last change the biggest problem was that for hot cities (Phoenix and Austin) it was too low, we now fixed that.
I'm in Phoenix, and it still seems a bit low.. about 16-20k off at lead with high experience... seeing roles around $130k locally. One of the sites like glassdoor is seeing an average around your top.
For U.S. it may be best to establish a floor, and for most cities don't go below that... Remote work in the U.S. tends to be closer to 65-75% of Northern California pay, from what I've seen. Often more than local rates, but harder to come by the jobs.
Edit: and yeah, I've read a lot about your company including that link. I understand your approach, it just excludes me.
