What is the Gap between SSJ Vegetto and Boohan?

[kriss-]

Goku fought Frieza with a Kaio-Kenx10 during the majority of his fight with him, while Frieza was only double Goku's power. Yet he was able to fight him with his legs. Vegetto performed the exact same feat against Boohan.

At minimal - it's a 2x gap
At most - it's a 50x gap
