about 15 seconds...I feel like 30 seconds is a long time.
Around 15 seconds from pressing the power button to the login screen.
Again, thats not possible. You're trying to tell us that either your Mac skips all of the POST process or it simply loads Leopard in 2 seconds?
Getting to the login screen doesn't necessarily mean its finished booting/loading up either.
5 seconds. On a good day I get 3 seconds.

Joking. I timed mine, and it takes about 27 seconds. But mine's new and i still have about 95GB out of 160 free.
From completely powered off to dock?
You must have a SuperMac Pro.
