Dihedral, again

[swOHJon]

Hello,
I understand from previous post on this topic that the spar root angle is intended to set the proper dihedral of the wing. But I also expect I can do a less than perfect job gluing the root ribs against the spar end, throwing off the dihedral. Right now I get about 4.25" under one wing tip when the other panel is flat on the table. I'd like to check my build against the design intent. So, please, can someone tell what the intended dihedral is for the Wee Papillon?
Thanks!
Jon
