So the 1.103 update mentioned changes to the energy network, but it doesn't seem anyone has documented the changes, or at least updated all the wiki's with the pertinent information, which implies to me that people either aren't aware of the changes, or else are keeping them secret. 
Anyways, it seems that cable spitting no longer wastes EU. I can't quite figure out how the new system is doing this though, could anyone help analyze this?
