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.

Broly was ragdolling Goku and vegeta in their God forms.
(SSJG shook the universe while fighting Beerus which is Billions of light years).
And keep in mind Beerus even admits Goku is formidable (I know he was holding back but this could mean broly could scale to lord Beerus when he is using that level of power)

Now Beerus Just by trading blows with Champa could have destroyed universe 6 and 7

And once he went SSJ he was Shrugging off attacks from SSJGB Goku and vegeta in these forms they are way more powerful then SSJGB.(even before He was still training blows with Goku blue even tho he was losing until he went berserk and transformed into SSJ)
Overpowered The Golden frieza with little effort.

And remember what I said about Beerus? Well Guess what Goku even states this.

And he even learned to master his SSJ Transformation currently
So unless room has anything that puts him at least at low multi He is getting soloed by broly.
