I'm not sure if there is anything for konami to address in this. It just takes time to adjust to. I don't personally use it anymore because I found it too cumbersome to use.
It seems there are two options, manual and advanced. In Manual you control the height of the ball with the power up. In advanced you control the height of the ball with the stick. Maybe there is technically more control with advanced, but I'm not sure if it really adds as much to the experience as it demands.
