Another question for the experts...

Roll rate, within maneuvers. The rule book talks about rolls being centered on lines, and roll rate being constant during a roll element, but here is an example.

A "combination 8" with the first leg having two negative snaps and then two 2 point rolls opposite. The 2 point rolls will have a fairly high roll rate (unless one starts this maneuver at 1000 feet). Then the next 45 degree line contains 1 1/2 rolls. Do the 1 1/2 rolls have to have the same roll rate as the two 2 point rolls on the first segment?

Another example is the braintrust maneuver during Thursday's known. You have to trust your brain to roll through 2 rolls and not pay attention to the fast approaching ground. Otherwise you crash. You see, after exiting a figure 6 at mid box altitude, a center humpty from the top is next. The two rolls down will have a fairly high roll rate, then the negative snap on the upline is followed by an opposite 2 point roll. Does the 2 point roll have to have the same roll rate as the two rolls down? I'm also interpreting a higher exit altitude than entry altitude is ok (or vice versa).

After studying the rules, I believe that the roll rates for each independent line segment do not have to be the same, however I defer to the experts...
