97-98 cents per dollar, excluding control on overdue hours. Twice more men than women do unpaid hours every week (34% vs 17%) leading, each year, to 3-5% more experience per year. Therefore, 97c for 5% less experience per year worked, and the wage gap already goes the other way.

And we can’t measure the quality of the focus per day, obviously. (But we can measure the toilet time. It’s mean but results always go the same way).

And from what I recall, unmarried women with no kids actually earn more than unmarried men with no kids, and have for several decades.

I thought that number was a much stricture control. I think you have to do a lot more go get to the number you're talking about and there's no explanation for that one. It's been a bit since I looked but I don't think things improved that much. Even still, a 1% median difference on earnings is a pretty large number.
