Ooooh.
I now understand.
I read this: "No one now not manipulate rating values."
To mean that EVERYONE is manipulating rating values!
It's only in @hedkeaf's last post that I now get what he was talking about.
I also got mislead by hedkeaf's extremely low metal usage graph in the linked game, only when looking at the replay can I see why that happened. (@hedkeaf: you need storage to be able to receive other player's excess energy, which you need to build your own stuff, if your com dies in a teams game you should immediately build storage)
Sorry hedkeaf, misunderstanding.
