Camera Speed 8 Not Fast Enough!?

Testing different methods besides World Composition. Crossing maps can be VERY lengthy and time consuming. Camera speed 8 is not fast enough, even with RMB + Scroll Wheel. I tried changing the speed in the Editor Preferences, but it reverted back to 8 and would not accept the custom speed. How can I change the speed to 100, instead of 8?

Agreed. Did you ever find an answer for this?
