As your PL increases, it will become increasingly unrealistic as you will be able to use seemingly endless devastating power moves (for instance, when you are at 1,000,000 PL, you have 100,000 KI points, which would equal 1000 Kameha-Mahan's, which is ridiculous by anyone's standards), so not only moves you can do, the KI points for the moves also increase with PL, which also increases the damage of the move.
IMPORTANT - these KI increases take place at every 1000 increase of max PL, so after you have gained new PL from training or whatever, then move KI will be changed accordingly. It would be helpful if you could post up the new KI for each of your moves every so often, as neither of us will have time to update move KI for every character, especially when you have a lot of moves
NOTE - There are calculators for all of these on the calculations page, so you needn't worry too much about it. Read on though, so you understand exactly how the sytem works.
The method, which is easy is to work out:
Added KI = (PL/100, same as 'Max KI') / amount possible, -base KI, then add required KI for your move
Here are each move power categories, with calculations and descriptions:
Low Power (A) - calculated so you could use all your KI to perfom 1000 of these.
Medium Power (B) - calculated so you could use all your KI to perform 100 of these.
High Power (C) - calculated so you could use all your KI to perform 10 of these.
Devastating Power (D) - calculated so you could use all your KI to perform 5 of these.
A - base KI of 1
Calculation : (Max KI) / 1000, -1, +KI required for move
B - base KI of 4
Calculation : (Max KI) / 100, -4, +KI required for move
C - base KI of 10
Calculation : (Max KI) / 10, -10, +KI required for move
D - base KI of 100
Calculation : (Max KI) / 5, -100, +KI required for move
