how big was Fused Zamasu's power up (manga)

[KyuubiAhri]

When he was choking goku and vegeta he did a power up.looking at his comments after,it ought to be huge one.How high do you think it is?

 

[Captain Cadaver]

Even 20% or less can be huge if the plot demands it (eg. Vegeta's power up in the Saiyan Arc), so it doesn't really need to be anything huge. He was already speedblitzing them beforehand anyway, so their comments in general were justified even if the power up wasn't that great.
