With finger joints it's at least as much about the bit as the jig. A
dovetail you can adjust by changing the depth. With a finger joint bit
and
a jig either the bit's the right diameter or it isn't. It might be
possible
to design a jig that allows the spacing to be altered easily by 1/100s of
an
inch but I've never seen one.

You're right; it is possible, but...:

I have found that the best way to adjust this type of jig is not to move the
reference pin, but instead, to move the blade by adding or subtracting
stacked dado shims.



Building a well-adjusted BJ jig is very fussy. The alternative is
using a DT jig with a BJ template (you might as well buy the stock).

What's a "BJ" in this context?

Box joint (a.k.a. finger joint) implemented on a "dovetail" jig.
