Well concerning 10 or 25+ degrees turns, I guess it all depends on the sectorization, the conflicting points, and the traffic flows.
We are told not too turn planes more than 30° unless for a quick avoiding action.
Moreover if you want to turn a plane just 10° to resolve a conflict, you have to do that well well in advance, and our sectors (I speak for Paris ACC) are maybe smaller than in the rest of Europe (due to the high traffic volume).
