Mr.L,
Even though I feel the game has a randomness factor, that might affect the results of the kind of testing you do (and believe me I've made a few myself), we all have to agree that the quantity of matches played are the key here. 180 matches does remove a great deal of the possible effect random factors might have in the results. Moreover it's important to realize that under certain scenarios there are a lot of tactics that work wonders, as long as motivation is kept high, so there will always be different opinions concerning the best tactic. Honestly after I saw it in your testing, I started using 3-4-3 Watford System V2 and after one season with it, I've to say beyond any doubt it is the best tactic I've tried. Thanks for your work mate.
