Question re calc stacking and power scaling

[Jasonsith]

I have been visiting the pages of powerscaling and calc stacking and some examples really disturbed me especially when visiting other fictional verses.

Examples of calc stacking that cannot be applied

• Character A moved so fast that character B couldn't react to him. So character A needs to have crossed the distance (say d) until he could be seen by character B again in the time that character B requires to react. Since we know from a calculation how long character B needs to react we can calculate the speed of character A based on that.
  • Here it is only calc stacking to say that Character A speed = distance / (character B reaction time)
    While Character A speed >= Character B speed is still powerscaling right?

• Character A has a certain speed through a calculation. He can not dodge the projectiles from character B from 2 meter distance. But Character C can dodge them from 1 meter distance, so character C has to be twice as fast as character A.
  • It is still safe to say Speed of C > Speed of B > Speed of A (ceteris paribus)
    Just we cannot say "Speed of C >= Speed of B" and "Speed of B >= 2 times Speed of A" right?

• Character A was calculated to be able to punch with an energy of 50 000 Joules. Assuming his fist weights about 0.5 kg, it needed to move at least with Mach 1.3 to get that much energy. So the attack speed of that character and the speed of everyone who can dodge his punches is supersonic.
  • I am sure this is more an issue of kinetic energy feat problem where "fiction in general differentiates between the attack potency and the speed of a character, and can return "unrealistic" values that can be inconsistent with other feats in the same fiction verse - as even a Small City level+ punch would already have Relativistic+ speed".

Any thoughts? (I find this bugging me when I am reading verses from Marvel and DC Comics to some verses lesser known or just built without much visits (like Yu Yu Hakusho)
