Ok see something
Let say in the movie broly base was 5 and vegeta base was 7 so broly base was rising and he met vegeta in base and surpassed him
Then broly got boost from his monkey form which was like 28000 I say that number cause it is the exact same boost as god to base
So broly as that boost and now adds his 50x form on it to match gogeta in base
And now adds a 2x boost to give him his current form
Then if you remove his mad monkey form
And give a base of 5 and he achieves god ki which is 28,000 and he has a 50x times increase
It wi be his power for blue and still weaker than base
