You’re not wrong there!
Yeah that was what I was saying about “some experience with manual settings”.
I kind of lump various things into groups. Hardwoods, plywoods, minerals, vitreous things (tile/glass), plastics, rubbers, maybe one or two others. I know where the ballpark is on all of them at this point, and can make pretty good guesses when I get something new. For example, I’ve never engraved glass, but I have done tile and they aren’t that far off. A quick materials test centered on what works for those things will dial me right in.
Same goes for plywoods and hardwoods (though hardwoods are a bit more finicky, world of difference between rosewood and maple, but you can get a feel for that too).
Anyway I’m not saying a central spreadsheet is useless, I just wonder if it helps that much after you’ve gotten your feet wet.
Testing my theory:
Tiles like hot and fast with higher LPI. I suspect glass likes the same. I’d jump immediately to my material test without even bothering to search. But if I did…

Seems like the theory is fairly correct, hot and fast with high LPI. YMMV.
