Sure here you go, if I remember it right they used a 5 pinch test instead of the more normal 3 pinch people can do on themselves. I found this one that used a three pinch method the mean BF% for pinching was 11.59% vs 21.35% with DEXA.

This is kind of my gripe with calipers for bf% don’t get me wrong I think they can be a good tool to measure change in body composition because if you pinch the same way it’ll show you changes happening but actual bf% is tricky and super dependent on where you pinch and how often. Based on your account I believe you that you were really low bf% because it was the same for me, I err on the side of skepticism because of just how much broscience there is out there.
