It appears that Garretts filters are right on the screen.
Some need to push the limits. Some like to tweak, I get that.
What do those “presets” on the D2 and Manticore do? Nobody really knows unless you have direct ties with the factory. When does one filter act against the other?
If you need to push the limits, you need to do a lot of testing with only vague documentation.
I’m done with that ambiguity game. I need facts to deal with.
But I might be jumping out of the frying pan into the fire …
