EV's were definitely falling as the test progressed. 5.6 to 6.3EV's. So this is another variable that requires attention. I can take the set up to the basement, but that would mean installing the software on my laptop... IS there any limitation on number of machines this can be set up with?
Yep - stability and lighting. One can compensate for the other to some extent (more stable means a slower shutter can work, more light means a faster shutter which mitigates vibration). Looks like you may have issues with both. I'd move it to the basement and add a lot of light.
The FoCal manual recommends at least EV 8 (IIRC, the earliest version of the manual recommend EV 10). One reason I used the extra light even outdoors was that I was using a long, slow lens (f/4, f/5.6 with 1.4xIII), and I wanted shutter speeds as high as possible. At 15 EV, I was at 1/2500 s with the bare lens and 1/1250 s with the TC.
I don't know that there's a limit. I can tell you that I've got it installed on one Windows machine (a virtual machine) and two Macs, and I've run it from all of them. Since you have to connect a camera with a serial number listed in the License Manager, I suspect that's their control mechanism.
I am still a bit concerned since even with MF, I am not getting mind blowing sharpness... I guess i will run some more tests and then form an opinion.
If you're not getting sharp images with contrast detect AF and a well-lit, high-contrast subject, you may want to exchange the lens...
