This is a simple principle, but an important one:
If your basics are good, as you gain more power and speed, the movements will be stable.That is why it pays to take your time and learn your basics well. For instructors, this is why it pays to take your time and teach the basics to your students well.
If you basics are bad, as you gain more power and speed, the movements will fall apart.
It is like the propeller on an airplane. At slow speed, flaws or imbalance in the propeller will probably not cause too much of a problem. But at high speed, the propeller will fly apart and destroy the airplane -- and cause a crash.
With good basics, increased speed and power makes the movement feel even more stable -- like a perfectly balanced propeller!
