Here is how I understand it. There may be some fuzziness in the details, but it's a good way to think about it, well for me atleast!
Q value- This is a value that your tx interprets how "clean" the telemetry signal is. This is a measure of how your receiver is transmitting to your transmitter. It ranges from 0-99 and numbers (I've heard) from 20-50+ are OK. (I will be crucified here, but, oh well)
A value- This IS THE most important number to look at. It ranges from 0-9. This number evaluates how well your receiver is receiving the signal from the TX.
I understood somewhat different:
A = Strength of the signal received by the Rx. Kind of like a "volume" of a TV.
Q = The quality of the data received by the Rx. The number of GOOD data frames received, divided over the TOTAL number of frames, resulting in a percentage of GOOD received.
As such, Q values are the most critical as it was ultimately the Rx needs (good data).
We do need to be aware that we only "see" the data as transmitted by the Rx back to the Tx. That links is not as robust, so we may lose some information.
