I think I might have heard something about the shell being 10% slower on AGDQ, am I right or wrong about this statement?
It's slower by about 8%. Like Tedder said, you can let go of the run button, then re-press it while in midair to get back up to top speed; this is called "unmorphing". You will also see top players bouncing off enemies and doing double and triple jumps in the shell, which have the same effect as unmorphing. The double and triple jumps with the shell have a 1/30 second window to pull off, but you can get them very consistently with practice.
