Got it, that aligns with my understanding of how the system works.

The video is great indeed. Looks like dropping a sand bag, just a little more viscous than that
I presume with a regular bump stop on the same rig the weight would bounce back up, and that's what you call "bottoming out".
What I call "bottoming out" is "the damper is compressed to the point it can't compress anymore, or to the point it resists further compression at a rate much higher than the spring rate".
In other words, when suspension no longer "works": impacts from bumps are transmitted to the chassis, and the tire has reduced traction.
Having that said, for a HBS to prevent the tire from interfering with stuff around it, the damper body length should still be adjusted correctly. When it comes to RC / drop spindle kits that lower the car compared to stock suspension, that means the damper body should be proportionally extended relative to settings used with stock suspension.
