This pinch weld is one of those unintuitive designs that may be mechanically sound, but will keep confusing everyone to no end, because a few thin sheet metal edges will never appear sturdy enough to hold up 3600-4000 pounds without bending, welded high strength steel or not.

100% agree ( confusing and somewhat concerning)
I ended up buying magnetic flat bottom jack pads, rubber slotted jack pads and permanent screw type jack pads. The permanent ones are still in the box. After reviewing the fitment / potential failure points, nothing about any of the products makes me say, wow I feel really secure. I’d never lay under this car and start tugging at things while lifted (even with jackstands). Personally, I like the flat bottom removable pad best for my type use. It seems to be the most secure for weight distribution, with its larger physical size and stable flat bottom (I’ll use for removal of wheels and brakes)
For me, under car work = Race ramps....
