I was thinking that the SSJ Multiplier for Broly has to be much higher than 50x, if we want to make Broly SSJ higher than UI Goku (ToP)

[SIAD]

All this I say because the SSJBE Multiplier is between 25-50x the power of the SSJB in the Anime.

Vegeta SSJB (Broly) narrowly surpassed Broly Ikary, but his SSJBE form did not compare in the least with Jiren, while Broly SSJ surpasses the power of UI Goku (ToP).

That is why the SSJ Multiplier for Broly, must be greater than 50x his Ikary form.

You could make an argument base Broly or whatever the fuck he was in the film is already that strong in the film.
