The formation and style of play is a strategy. The whole club is set up to play like this.
It takes time to implement and refine and it takes time to get the right players in the right positions.
SP has chosen this strategy. He won't change it but keep at it till it works. He just signed a four year extension so he - and the club - is serious about sticking to the plan.
There is no plan B. It's about us playing the best way we can and not getting confused by different formations.
Sure, the opposition will take notice and try to find ways to work around our system, but let them do the changes and we can stay comfortable in doing what we are used to.
We will lose some games but eventually it will be fewer losses and more wins.
You don't change a strategy every few weeks or months - you stick to it and only make moderate adjustments to optimize.
I think you are confusing strategy with tactics. Nothing that goes on in a game is strategy. Strategy is the overall vision of the season, what we want to achieve and how we want to achieve it. The most fundamental aspect of strategy is having the right players (and manager). Tactics is how we implement that stategy from game to game. Tactics can and should change from game to game depending on the opposition and the situation at hand.
