I see about 3-10mv difference in the middle 75%.
At the top, i've seen 10-15mv difference over dozens of unbalanced charges now.
Below 3.6v, on good packs, it's usually 10-40mv, increasing to 300mv down into the 3.0v zone.
Now, a really good diagnostic is logging a charge and discharge with a celllog 8s. You can hook that puppy into USB and run it with logview to get the same graphs i produce with my iCharger 1010b+; pretty cool.
If a cell is constantly getting knocked out of balance, there surely is a reason for it.. either low capacity or a lower or higher internal resistance..
