Maybe this will help It is for the EVE 35V. Many cells will show a discharge to 2.5 volts and discharge termination at or below 0.1 amps.
This would give a bit more indicated capacity than terminating at 3.0V. Even at that, I am happy when I get capacity measured at 90% of the labeled or claimed capacity. So if you tested with the same parameters that they used and your meter it accurate something like 3150 -3200 mAh on a new 35V cell is not bad. Bottom line is that that cell is not measuring bad for a used cell.
