Fin toe in on grom boards

Curious what you guys are doing for toe in on grom boards.  Are you aligning off of the nose of the board (this is what I've been doing using a streight edge to a point  3/4 of an inch off the nose.) or are you going with a fixed measurement off of the stringer.  I've been doing a few grom boards and have two more to do in the next couple of weeks.

 

hahaha, I see what you did there
