did BF intonation installs for years back when it came out, but there's a reason nobody cares anymore (including me)
just like any other clever offset scheme, it makes some notes sound better by making other notes sound worse
the nut (in this case the zero fret) might be moved slightly towards the bridge to "fix" the first few frets being sharp, but that can and should be fixed by filing that contact point properly so the string is not too high over the first fret to begin with. yes, even if it's a zero fret, all too often they'll put way too big a fret in as the zero fret causing bad action, that needs to be filed down just like any other high nut slot
were this bass mine i'd make sure the strings were properly low over the first fret, then tune and intonate normally
