I thought that "run up" was more a kind of accumulation in front of the edge

It's a good indicator for bevel and stroke but just like the hht it requires interepretation imho.
Slurry breaks the surface tension making it easier to get a false positive.
Moving the blade faster also helps to get water on it.
The water will also flow easier up once the upper side of the bevel is wet.
Using the blade at an angle will allow the water to flow easier from one side to the other.
Rasing one side of the stone when holding it does the same thing.
