You have to do alot of work just to find their speeds. Like first you have to look up how far they can travel in a set amount of time. Then you have to find the scaling for distance in the game and then caculate and convert.
You can't be exactly sure how strong they are because they don't die from realistic hits like say if i slice you down the middle all you do is bleed a bit but your still alive that's just unfair.
Because of this anime vs. videogame characters are normally one sided.
I am actually dealing with a abundance of this problem since i am facing one in a tourney. If you ask me i don't believe a word this guy says because i don't think final fantasty using a meter count so unless i get statements from the developers i consider them to be false scans
