Bessa R3A Patch doesn't reach infinity

[Kumachrome]

I know there's been other posts about this, but they don't seem to have the answer. Maybe this'll be different.
My R3A doesn't focus to infinity. It's little bit before infinity. However, checking the lens (7 artisans 50mm 1.1) the lens focuses to infinity just fine. I'm using a target that's well over a mile away.
The strange thing to me is that the camera focuses accurate at close and mid distance. But, past say...100 meters or so, the rangefinder just doesn't seem to...make it. It's short. The lens, however, is spot on.
Now, I know that since something is very far, I can just set the lens to infinity and know it's correct, but is there a way to fix this? I've also calibrated the lens exactly how 7artisans shows, making the focus pin point accurate at most distances. Any suggestions would be appreciated.
Thanks for any help!

Maybe the focus shift in the F1.1 is corrected because the RF is out on your body.

The body should match infinity on the lens. Everything falls into place from there.

How are you checking critical focus? Are you looking at scans from a flatbed? I would say that flatbed scans aren't a good way. With the resolution and post sharpening done to flatbed scans they really don't show whats ACTUALLY in focus.

I'm using a piece of tape traveling perpendicular to the film guide rails and looking at the center of it as my focus point. Hmm should I recalibrate the horizontal alignment on the body to match the lens at infinity?

I would realign the rangefinder at infinity. Do you have another lens to test if the R3A is aligned at infinity? I made a mistake trying to align my R2 not realizing that the 7a was serverely off in focus. I had to realign it with a more reliable lens, then recalibrate the 7a afterwards.
