I have three scenarios that all present an 8% increase in different ways.  How is this actually compounded, because they are VERY different.
Below are my examples... Which one is correct for cRPG?
      
A           Damage      B            Damage      C            Damage   
Level 0   10.00         Level 0   10.00         Level 0   10.00   
Level 1   10.80         Level 1   10.80         Level 1   10.80   
Level 2   11.66         Level 2   12.53         Level 2   11.60   
Level 3   12.60         Level 3   15.53         Level 3   12.40   
Level 4   13.60         Level 4   20.51         Level 4   13.20   
Level 5   14.69         Level 5   28.71         Level 5   14.00   
Scenario A is 8% compounded per level from previous damage increase
Scenario B is the value of 8% added to the previous percentage value (IE: 8% level 1, 16% level 2, 24% level 3)
Scenario C is 8% from the base damage of (10) added to each level (IE:  10.0+.8, 10.8+.8, 11.6+.8)
Which scenario does cRPG use???
EDIT:  Scenario B is incorrect and should not be displayed.  My error.
