The core of FM24's top tactics should be the DM-S+DM-S combination, which is more stable and has a higher limit than other defensive midfielders, which I have experienced especially in online games. This tactic is also the one I use most in online matches.
only "Tackle Harder" in every position，I think other than the key PI of "Get Further Forward" and "Move Into Channels", it's hard to say how much difference will be made.
I think all I can say is that this result is accurate at the two fixed combinations.none, overlaps, and underlaps are different for position duty selection and optimal selection for PI. I tested a variety of different 4231 Settings early in the release, both single-player and online, and couldn't come to a conclusion about which was stronger. Moreover, only with an ST formation can the attacking mentality compete with the balanced mentality, but the attacking mentality is stronger than the attacking mentality in the online game. 4231 is indeed a top formation, but it can occupy the top or rely on more test samples and luck, because 424 and 4231 are the first two tactics to occupy the top for a long time, so we fine-tune the test too much. There are actually some formations that don't lose to either.

Remove "focus play down the right/left"
Remove "underlap right/left"
