Using the twist method, I'd say that you definitely do not know how to adjust valves.
While holding the rocker tip down against the valve stem tip, jiggle the pushrod up and down and tighten the adjusting nut until all play is removed. Tighten the adjusting nut another 1/2 to 3/4 of a turn to set pre-load. Done.
