The Superhero Database Classification number, or SHDB Class, is a number that represents the overall 'power' of a character. All traits of a character are used for calculating the Classification.
What it DOESN'T mean
This doesn't mean that a higher class would always beat a lower class character. But the bigger the difference in Class is, the more obvious it is who'll win in a fight.
How is this calculated
( INT^1.3 + (STR*0.5 )^2 + (SPE*0.5)^2 + DUR^1.6 + (POW + (SPS*SPL))^2 + COM^1.8 ) ^ TIER
Super Power Score and Level
Every Super Power has a score (SPS) that is used to calculate the Class. Each Super Power also has 3 levels (SPL). The level is set when connecting that Super Power to a character. The level determines the final score, of the Super Power, being used in the calculation.
And Hulk has to hold back immensely when he runs because he's so strong his stomps shatter the ground beneath him. Its why he prefers to leap than run.
Reagrding Hulk's speed, he's been able to keep up with Dr Strange's Asteral form which moves at the speed of thought.
According to Marvel the speed of thought surpasses the speed of light.
World War Hulk is Savage Hulk with a sword
Immortal Hulk is the rawest and purest Hulk
Maestro is an evil Hulk from the Future Imperfect storyline who was made canon by the Ghosts of the Future storyline
And Professor Hulk is smarter than Banner.
Base Savage Hulk can figure basic stuff out meaning he's far from the mindless idiot you think he is and he has training as a gladiator as shown in Planet Hulk. Read Greg Pak's Hulk run my friend.
I don't feel like proving Thor's speed to ye again.
Maestro happens when Hulk goes insane and takes over the planet
Professor Hulk happened when base Hulk gained Banner's intellect at the cost of being able to increase his strength through rage. Again not changed in any other way.
WWH is literally just a really angry Hulk with a sword unless you can prove otherwise.
@Empty: you read a lot more on Hulk than I have, mind giving this guy 5 feats for Hulk's intellect?
2. Working with others to become ruler of singular reality
3. His mind allowed him to communicate with others when serperated from Bruce banner as he fought TOBA
4. When Bruce banner invented a virus that could harm iron man
5. Outsmarting red hulk by Making red hulk beat himself

Immortality - Not too sure, but I bet Hulk can die in some way. I mean, Immortal Hulk might not, but Savage Hulk has been harmed by attacks from Thor and Sentry.

Energy Absorption - That's radiation absorption.
---
Dimensional Travel - That's not dimensional travel, that's using pure strength to destroy the time barrier!
