Well here is the thing. I figured out my nodal points for a handful of lenes. Then I get the RC2 QR from Nodal Ninja (works and looks great!!) and realize I need to redo my nodal points.

My basic adjustment seems to be about 6mm for the B setting. The A setting was about 10mm and much easier to figure out. but I was wondering if there is an exact # someone calculated (ie more precisely than myself) for the offset of the NN3 with the RC2 and QR plate for the B setting.

Thanks in advance, this information could/should be very useful to future buyers of the NN3 and a RC2.
