The Thomas spin is a defensive and offensive skill, one of the essentials for an elite pilot. It is a composite operation with a difficulty level of 5, which, due to its inability to be generally adopted by the military, has been classified as a medium difficulty tactic.
The crux of all this is the choice of the mecha model. Using the old and heavy Phantom Knight 0001 model to do a standard spin kick is as challenging as a hundred-meter shot. It requires a proficient touch on the mecha, and you can't make any mistakes in terms of force control, hand speed control, or composite command input.
Keep in mind, most people couldn't perform it perfectly during practice, let alone in a life-or-death duel? Not only did the Revenge Shadow Rider 0001 do it, but the standard of the movement was textbook-level. This subversive result inevitably shocked the vast audience watching the light screen.
