Discourse search is kind of weak, you do need to think of it as a starting point and dig around a bit in the results. It’s tempting to think of people who ask and re-ask the same thing as lazy or newbies but the fact is that it’s not always easy to find what you’re looking for.
I still think if it were me I’d do my own tests; other people’s settings are at best a starting point. Really this is like any other plastic in terms of settings, and what you use will be driven by what end result you want, depth, smoothness, etc. Nobody else can tell you exactly how to get that combo.
