Does your CB hop up more if you break harder? Here's how I fixed that:
I've been using the BreakSpeed iPhone app since it came out, measuring most of my breaks in practice (and even in friendly matches) and making the adjustments that seem to make a difference (mostly being more careful to hit the CB exactly square).
My average controlled break speed (hitting the head ball square) has gone from 18mph to 20mph, and I'm making more balls as a result, but I also created a new problem: as my break speed increased the CB began popping up on contact with the head ball, and the faster my break speed the higher it popped. This wastes CB momentum that could be moving OBs closer to pockets, negating some of the positive effect of the speed increase (not to mention sending the CB on unpredictable trajectories), so I couldn't just let it happen.
Fortunately I'm familiar with the reason for this and knew that changing my break distance would have an effect. I reasoned that breaking harder must be causing the CB to take longer hops on its way to the rack, so I should lengthen the distance between the CB and the rack to compensate.
So as my break speed has grown I've gradually moved the CB back (toward the head rail) from my usual break spot and, whaddyaknow, it has worked great. In total I've moved the CB back about 4 inches now for an increase of about 2mph and the popping up has remained under control.
We've talked about this solution to popping up before - I thought a real-world experience with some actual measurements might be interesting and maybe useful.

P.S. My usual breaking spot was 1 ball width off the side rail, on the head string. I'm now breaking from 1 ball width off the side rail, 4 inches behind the head string. I imagine I'll have to keep adjusting this distance as my controlled break speed keeps increasing.
