HKJ describes what you should be seeing as the cell(s) charge, see his review
It will seem like a lot to read, but it’s all the info you need to understand how the charger is working.
Note how the charts show the voltage rising to 4.2v and eventually shutting off.
The mAh number is, I think, a rough estimate of how much has been put into the cell (you did not start from zero, but from some low charged level)
