I see, I think you should post some clips of you doing that drill for real then. FH loop against block is one of the most basic drills, and it's very pertinent to what you'd like to accomplish which is landing FH shots in a rally.That's a warmup. Even pros focus on feeling and weight shifting and don't move around. That's a bit harsh. As I said it depends on what my goal in each Drill was.
Again watch after Video 5. I think where I really have to move for the balls.
The most similar drill to that in your 10 videos is Video 8, although it's not as efficient as just a straight FH vs block drill as your partner has trouble blocking your opening loops. In that video, you can also see that you have minimal foot movement. For example, at the 1:30 mark the ball goes to your middle and you just chop it back rather than moving to loop it. In the subsequent point beginning at 1:39 you make two straight loops without moving.
Check out this video of Ovtcharov training. After the first minute of warmup exercises, see how he utilizes his footwork. In the first clip where he trains with I think Pitchford it's actually better to look at Pitchford's feet, how much he moves even just blocking. In the next one pay attention to how consistent the landing point for the blocks are, yet Ovtcharov is moving quite a bit to adjust to every shot. There isn't a single shot where he doesn't take a hop before the shot, even if he doesn't actually move an inch. This movement needs to be built into your shot, it's just as important as your swing. You can't loop without swinging the racket, you should impress into your mind that you also can't loop without moving your feet.
