Fed is still great when he can attack freely, and he could do that today. But like BroTree said, this means very little going forward because Janko can't force Roger to defend like for example Delpo can. And it is in defense (or rather, the transition from defense to attack) that Roger has declined the most.
Someone is listening.
Fed has to play a higher quality opponent to really see where his form is at. Janko had given him plenty of opportunities to attack, but I'm not sure if the other 2 guys in the group would let open a gap like that.
