you can proof me even some M.I.T. study about it,
YOU DO NOT SEE 2 INJURIES PER TEAM EVERY LEAGUE'S MATCHDAY.
In italy we have 20 teams in the serie A, and there are NOT 40 injuries a week. It is not nearly even half of that.
Your statistics take place with even light fevers, hemorroids or whatever else.
Another point: whenever you finish up your 3 subs, 95% of times one will injure.
ANother point: the lab's construction and leveling SEEMS like a good thing when you start playing, and basically it should be. Point is that it erases short times injuries and "limits" long times duration's ones. So after i'd say 5-6 levels, whenever one player injures you know already before checking that you have 25% of chanches of the injury being 2 days, and 75% of it being from 5 days up.
Another point: since Season two, each season my injury rate doubled, let alone that i never changed my method of training. I'd like to know how's that possible, to progress through higher leveled facilities, grass, fighting less hard tackling style teams, and cap 50 injuries in 28 days.
Point is that the more we play, the more they raise rates.
