Are you sure that is a real issue? Balancers are not 100% accurate either. Even components with 1% value tolerance can easily introduce enough variance to account for 0.01v. Heck, even dirty balance connectors can cause an erroneous reading. I would measure each cell with a multimeter to be sure.
And even if the cells are 0.01v off, that's nothing to worry about at all. Believe me, I'm pretty anal about having things properly matched. If you are worried that a cell could get above 4.2v because of this, just set your charger CC/CV threshold to 4.15v/cell, if it supports this feature. You lose VERY little runtime. Actually, I have my Xtrema set to this value for this very reason.
