I only used the multimeter for testing the voltage at 0 current.

For the current usage, I started with the data sheet values on the particular 758 I used, then I charged a battery fully. Went out and flew until the timer went off, then let the battery settle for a bit (15 minutes or so) and charged it back up on the exact same charger. After that I looked at what was reported on the Taranis and compared it to what the charger put back in and adjusted my mV per Amp value until I got it as close as I could. I don't fly till only 20% left usually I land at about 30% as a safety net.
