I do the same thing but use any small board. I simply put it on edge and
run it into a spinning bit until the wide part of the dovetail bit makes an
imprint - the exact height is guaranteed. It hasn't let me down yet.

One of the solutions I came up with to solve this problem for future
use...

Once you find that "sweet spot" on a particular dovetail bit / dovetail
jig combination, take a scrap piece of hardwood about 2" x 12" and run
it through a surface planer until the thickness precisely matches how
far the bit protrudes from the base of the router. I then drilled a
hole to hang it, put a coat of finish on it, and labeled it with a
marker so I wouldn't throw it out some day when I had a brain fart.

Now, when I set up to cut a dovetail, I get the router, the bit, and my
homemade depth gauge. After putting the bit in the router, I use the
gauge to set the depth for the bit and it always gets me VERY close to
the exact depth of cut. If it isn't right the first try, I usually nail
it after the first adjustment.

just my .02¢ on what works for me.
