Goku vs. Phoenix

[Farealmer]

There's a tendency for DBZ folks to argue using ABC logic, calculations and other things that are widely unacceptable as feats.

You mean like things used for almost every speed calc(and many other aspects such as damage, durability) in almost every anime ever. From Kenshiro to Naruto to Gatch Bell which is then not only used but accepted without challenge or question 99% of the time.
