Speed Graphic rangefinder adjustment.

So the last time I adjusted the rangefinder on my Speed Graphic I remember it being 14 degrees out in the mountains of northern New York. Since it was a beautiful 76 degrees out today and I recently did a massive lens swap on my cameras i decided to do it again.

I can't remember it being this hard! focus at infinity, adjust for that, focus at a sign at 25', adjust, check again at infinity, check at 15', 8' and 4' check infinity again. I was outside for 30 minutes trying to get a new 127mm Ektar dialed in. I did succeed, but it was a PITA. There has got to be a better way.

I have 2 more Speeds to adjust the RF on, one for a 135mm and one for a Aero Ektar. Before I go thorough all that again, is there a better, more accurate or faster way?
