I did a similar test myself on two bikes I have and it pretty much confirmed the results. If you ride on decent roads and it's not raining, the difference is minimal. This isn't on mountains but just flat to rolling roads.
The video shows the results a little less than halfway through
GCN needs to conduct a fair test: rim brakes paired with alu rims. Carbon rims provide a notoriously poor braking surface for rim brakes. It's likely the rim brakes provide slightly shorter steps in the dry, and are very very close in performance with some higher end wet condition pads such as salmon kool stops.
