Not sure what my data is worth, but I'll explain why I am not skeptical of Wiggans's figure(s).
The only times I've been higher than 6% is when I was on a break between seasons (measured with bioelectrical impedance on a bathroom scale, which cna be a cause for skepticism). I would usually go up to 160-162/74kgs if I took two weeks off, and tried to eat everything in sight. When I rev up for a season again, It doesn't take long to get under 160, when I would usually start to see a body fat % of 5.9 or less. When I got in shape, I never registered on the device (it had a minimum of 5%). I was in great shape at 151/69kgs, and spent most time around 154/70kgs. I'm 6'4", and a runner, so different timing and exercise than what were talking about...
But whatever. I don't know the research for the sweet spot between loosing mass and loosing power. It sounds like the science doesn't either, though. Every athlete though, does know, innately. I brought myself up as an extreme example of that, where my experience does not align with what the collective would predict as effective.
Like many things in performance, the science creates a general understanding, but past history and individual experience is much more useful of a guide for how to train. I think that Wiggans, as far as his weight goes, is just another example of this
