I don't think I got the true effect because as I said, it was one of those times where you start up FIFA and for some reason the whole game you are playing is not how it felt before regardless of whether you have altered Sliders etc. I finished the Huddersfield game and saved the file. I then shut down the whole game and restarted it and played another game, albeit with a different CM but with the +/- difference and the passing and player movement felt much better. Hopefully when I start up the Villa CM next time it will 'act' normally. It's hard to explain but I know other people have experienced similar things too. I'll let you know.
