I would say its that really split second..Trying hitting a normal flat hit but the last split second after hitting purposely flick your wrist forward and see the effect. More spin and becos of the spin the ball flying thru the air the arc or flightpath of the ball will be better.instead of a straight linear path when you flat hit. The arc will help flight go over the net, increasing ones consistent.
He’s just adding a lot of bullshit. It is not possible. Just look at his slow mo video. He’s not doing it either. He’s just doing it normally like everyone else: one motion swing forward+upward finish at around the forehead; forward for power, upward for spin.
