Kanzenshuu

Doesn't Whis say that it would take both Vegeta and Goku in this state to be equal or have a good chance at beating beerus?

I mean if that's the case, and Toriyama said that Goku's super saiyan god was a 6, where Beerus is a 10.

Meaning Beerus is like 1.6 times (or 40%) stronger than Super saiyan ...
