Why don't authors clearly state the damage and calcs of the feats when they happen? Something like a nice round number like the jules of energy or something rough by describing how much damage one single strike could do. For example:
*insert manga panel of goku punching freeza*
*narrator bubble with the following text*
>all of these punches are 6a max, while freeza is being actively failing to defend himself meaning he's 5c.
you get it?
