Those videos are really cool. They nicely show that you can configure your anatomy by adjusting heel height, stance width, and bar position. It didn't click with me before watching these videos that stance adjusts the effective femur length, but that's a cool observation.
There's this one guy in my gym who figured out how to get better hip drive with a long torso, by taking a very close stance and a bar position so low that the rest of us wonder how he even holds it.
