The idea came from raising grain silo vertical structures level on the farm with 8 hydraulic cylinders connected to one pump.... if one was not proportional, the tall silo would tilt and fall over when they were raising it for installation on tall permanent legs.
I use flow dividers to control exactly the same hydraulic oil to two separate devices in the case one device fails (seal or broken hose) and bleeds all that oil of that circuit, the other circuit isn't robbed of its oil because the flow divider still gives that remaining good circuit its share of oil.
Hope this helps you ....
