People often get this confused. You can't use smaller k-factors to balance the system calcs. For example you can't have K8 at the end of a line, then 5.6 in the middle and 4.2k adjacent to the main. This would be done to reduce over discharge.
This is not what you are doing. It is no different than having extended coverage and standard coverage in the same room.
