Yes, got it and that's a very nice slope.
My problem is on LFDZ scenery #62864, just uploaded on gateway few days ago: the previous WEDbot one #20166 had also a good slope but had wrong coordinates.
When I aligned it with Wedomaker help, unfortunately the slope became very bumpy and the runway was impossible to fly. I fixed this with Always flatten option but I am not happy with this: I don't like it. Suppose it is because the runway is on the top of a hill and I encountered a very specific situation.
That"s was the dilemna: wrong coordinates and good slope vs real coordinates and in this case broken impossible slope. That's why I was frustrated to not be able to define the slope by myself. If you have some time to have a look, I wwould be happy to have your feeling.
