Very good point about the reference beam. I haven't thought about that.
It may not be a problem though, as the wave front will remain symmetrical, I think, and it should only affect the amount of spherical aberration seen. A good question is whether it will add or subtract from the 0.5, and I'm assuming that I can hit the vertex of R1 with the reference beam.
And thanks for the ray tracing too - you saved me some time.
