You will probably need an assistant. Multiply by 1.09, this is teh starting point for the distance between the center of your saddle top and the center of the pedal spindle, with the cranks aligned with the seat tube. This is just a starting point, and may need to be fine-tuned as you ride and feel things out.
As you move the saddle forward or backward, you may need to raise or lower it slightly to restore correct height.
"... would be double at teh cranks ..." ?? I don't think this makes sense, can you clarify what you mean?

The bike is feeling a lot better. The measurements from the floor gave me a good basline to start. I ended up moving the seat forward and upward a few mm.
I don't know if its feeling better because I've spent the last week on it or because I've spent some time dialing it in.
I am considering shelving the beautiful Campy pedals and installing a set of Shimano SPD's I have laying around as the Campy pedals are getting scratched up.
I guess double at the cranks is the wrong way to vebalize what I was trying to say which was moving the seat up or down effects both the up and down stroke of the crank arms.
