Maybe Vegeta's training made his so strong that once he finally got a large enough lead, Black's Super Zenkai wasn't enough.
Like, he is getting stronger, but Vegeta is so much stronger Black may as well be Vegeta post Zenkai to Vegeta's True form Frieza.
It doesn't make any difference.
One Strip! One Strip!Honestly, I can't really understand how Goku and Vegeta haven't surpassed Beerus by the Universe 6 Saga. Beerus had to use over half his strength against a regular Super Saiyan God, and Goku and Vegeta had three years worth of training in the Hyperbolic Time Chamber after they achieved a form that was stronger that the red Super Saiyan God coupled with how we there's no indication if Beerus got stronger after meeting Goku and Vegeta...yeah I don't really know how.
I guess if you train for the sake of something you care about in the Dragon Ball Universe, you'd get much stronger in a shorter amount of time considering how strong Vegeta's gotten in only six months of training.
Well, Power Levels are bullshit I guess

Hey guys, should we move Beerus and Whis from the Dragon Ball Z Movie Villains page to the Dragon Ball Super page?
...
So....who do you think would have won between 17 and Piccolo if their fight had continued?
One Strip! One Strip!

Its nice to know Zamasu is aware at how narcissistic he is, you don't get that a lot in villains like him.
A lazy millennial who's good at what he does.
