There is no factory default: James at Alembic will aim for the same feel and the same 'neighborhood', but they will all adjust to that place slightly differently, due to all the little vagaries in each piece of wood, the total of the little tolerances in construction, etc.
Generally, for low action, you shoot for dead straight and then 'back out' just enough relief to kill most of the obvious buzzes. When you get to that spot where the neck is carrying only the slightest relief and you can hear a few string rattles that don't carry through the pickups and out the speakers, you'got about all you're going to get. All of this changes with personal taste from one guy to the next, playing styles (light touch, slapper, heavy pick, good or bad left hand technique, and on and on), string type and brand and guages, there can be a lot that goes into it.
And some guys can play anything and don't notice, all the way to guys who can feel and tell everything wihtout even plugging it in.
There's a lot that goes into setups, but it really depends on the guy playing it as to how extensive the work needs to be. In general, Alembics are very easy to play, and easy to maintain.
