I absolutely 100% totally disagree with this statement!
On MD#5 you roll balls up and down the table, just hitting center ball. and what happens if i have to hit a ball with low left? there is no comparison. none whatsoever.
Yes, ND#5 requires you to roll the ball up and down the table. But while you are doing it, you should be learning something. You should know what those different speeds feel like. Then you have to take it further, and apply what you learned to various shots.
Whoever said knowledge is power was wrong. Knowledge only becomes power when application is included. Knowing how to shoot a 5 speed in and of itself is useless, as you stated. Knowing how to use those different speeds in a game situation is what your goal should be.
Is that really that difficult to comprehend?
