Those are my measurements on my Z3,
Sorry it's not an AB, and it's in metric system but feel free to translate those,
(All measurements taken in playing position with the bass perfectly tuned)
Neck curvature: 0,25mm
Action at 12th fret:
G= 1,25mm (I like my G exceptionally low for slapping and tapping)
D= 1,50mm
A= 1,60mm
E= 1,80mm
B= 2 mm
It really is a nice constant hill for me, I don't follow the radius of the fingerboard for the thicker strings because of how they vibrate, but that's just my personal preference, and I set all my basses around the same, they're a joy to play and buzz just enough when attacked to sound really nice, doesn't buzz if played smoothly
My LeFay is even around 0,25mm lower than all these numbers respectively! But I believe the radius is much flatter on that one as well. The difference in comfort isn't that shocking even though it is easier to play, it doesn't sound as impressive.
PS: If in another life where I play with a pick (which I almost don't), I would keep the neck curvature of 0,25mm, and raise the saddles for about 0,50mm each respectively. Or add 0,25mm of curvature instead, maybe that could work nice too
