Is There A Problem With My Powerex MH-C9000 Pro Battery Charger Or Is The Problem Me?

Thanks to Dennis for his comments on the last video about remarks I made regarding inaccurate readings of the Powerex charger. The method I have been using to analyse capacity is to completely discharge the batteries first and then to measure how much charge they accept when charged. This seems to work well with the Liitokala charger, but results in ridiculously high readings with the Powerex. Why the difference? Can anyone explain? Is there a problem with the Powerex charger or is it user error? How can the reading be 3,700mAh when the battery rating is only 2,450mAh? I did some research today and it seems that I have been doing it wrong. I therefore did another test, first charging the batteries to full capacity and then performing a discharge to see how much power the chargers removed from the batteries. When doing it this way, the results from each charger were closer but the Powerex readings were still significantly higher than the Liitokala. The results from which charger are likely to be more accurate? I favour the results from the Liitokala because these are closer to the actual battery rating.
