Very satisfied with this run for the Hell% category. I guess it is possible to not have to change the cavern parameters in the advanced world gen and still not breaching caverns and finding the adamantine vein directly, but all of this is purely based on luck. In this case, I already had to be lucky to find a adamantine vein in a 1x1 map (you have one chance out of 4) and a cavern that is not too annoying to cross (no water or deadly creature).
