Literally my first thought. Aint much droop, or stuff going on with those vehicles. And usually thats a huge indicator of offroad performance.
Those tests are interesting... but mostly they just look fancy. Anything with locker( one, or two) and angles enough to not cause ground contact issues, will do pretty well. Especially on "flat" ground there (the ground isn't flat, but the gradient its driving on is flat. It would be much more difficult if that stretch was the same, and all "uphill").
A vehicle with enough articulation won't even have a tire come off the ground in the same situation. This sounds like hyperbole, but, I had a buddy in high school who had an old K5 blazer with extensive mods (drop shackles, dual transfer cases, negative offset wheels, police cruiser fuel injected V8, full cage, etc, etc, etc). He could drive over a 6ft tall RTI ramp, without any other tires leaving the ground.
An RTI ramp gives you an RTI score(Ramp Travel Index). Basically, you drive up an angled ramp with one wheel, and divide the distance traveled up the ramp, by the wheelbase of the vehicle, and you get a score. By buddy literally drove over the end of their ramp without the other tires leaving the ground.
Think something like this.

I guess they're useful for showcasing rigidity of the unibody? The R2 having lockers, and decent angles still does mean something. But its clearly not designed to be an amazing offroader. And thats not a disparaging comment. Its still more capable than most compact SUV's. Its just clear this also isn't a Wrangler Rubicon competitor, which is fine, it doesn't need to be.
