Has anyone used Reikan FoCal for autofocus micro adjustments? Thought on whether it helped?
Please don't make this a topic of why autofocus micro adjustments are bad

I found it useful for primes. Not sure what to say about the zooms. Have you tried with your Sigma zoom that can be fine tuned with the USB dock? The combination of the two processes could be problematic.
I would repeat the test with the same camera, and the same lens, with the same lens, more than twice, and there would be a range of sometimes up to 5 points. I am sure because autofocus always has range of outcomes.
