If you check my back posts, I explained in more detail how I go about teaching the break, but here it is basically.
1. You have to learn to control the CB FIRST, power comes later. Break the balls with whatever speed you want as long as you can park the CB after contact with the rack. Then you can ramp up the speed as your control gets stronger.
2. Once the control is there, WHERE to break from is the next thing to figure out on any given table. I start wherever the most wear is in the kitchen on the table, and break at
1/2 speed. Most people always try to crush the rack when a soft break works better, but they never find that out. then adjust CB placement, and ramp up speed accordingly.
3. Next....when you are really breaking well, look at the ball placement in the rack. If the wing ball is going, and the 1 is going up table missing the side pocket, play position for the 1 accordingly. Or...play the percentages...If the 1 is going in the side, wheres the 2 racked, and where is it going to go? Over all keep the CB in the center of the table for best results.
4. Now...when you really get into the study of the break.....you'll get possessed with ball placement in the rack. There are combinations when racking that make it better for a run out, or tougher.......that's another post all together.....can you tell I used to obsess over breaking?
have fun
