The SNR units should be standardized into a single metric, something
actually useful like ESNO or db. If that isn't available then we should
aim to eyeball / manually calibrate impossible boards against known
reliable demods on the same feed, it should be close enough.
This requires patience and time from the right people with the right
hardware.
