Many people-- and perhaps this is a valid method, I don't know, take a kind of atomic-reductionist approach to creating their stroke.
If a the analysis of a hundred good srtokes shows that there are 12 common points to each one, then this sort of person tries to immitate each one in bits and pieces and ultimately connect them all together like an elaborate moving puzzle.
But, to me, that seems a bit backwards. Most of the elements of a good stroke are smooth, effortless, and part of a continuous, fluid motion, that conforms to the physics of the game and the natural motions of the human body/frame/skeleton/muscles...
Most of what happens during a stroke is not forced, or even thought out in the sense-- at point "A" I twist my wrist to this position, than at "B" I muscle it to this other position, then just before impact with the ball, I make sure....
Anyway, I think very few really good players learn that way.
Imagine your wrist is a hinge (which it is) and the racket a sort of pendulm (a stick with a weight on the end), which it is.
When your racket is back and you swing it forward toward the ball, what happens at the hinge? Does it stay straight and rigid or does it (due to inertia) "lay back" until the weigh reaches enough speed to begin swinging around- forward- almost of its own accord?
OK, keeping the pendulum analogy, when is the force of the weight the greatest- when it is angled back or straight out?
SO, I hope this is fairly clear. As you get the racket head in motion, it is just natural for your relaxed wrist to "lay back" and get the motion started. Then, as your arm goes forward and around the head speeds up and your wrist begins to straighten because of the natural forces at work.
By the time the racket face impacts the ball your wrist is very nearly straight, with only a very slight motion as you followthrough the ball.
So, just for practice, imagine there is a ball right in your "strike zone". Hold your racket is right there, perpendicular to the court. It should feel comfortable, stable and natural.
Now,take your racket back and just pull and swing, loosly and freely through that point until there are no hitches- nothing forced or labored. Try it on both the forehand and backhand.
Watch yourself in a mirror or picture window. Compare your stroke to the pictures in books or your favorite player.
If you can do that, the bits and pieces will take care of themselves.
