New Formulas Simplified

Perhaps this is some sort of linear formula, whereas it calculates the added crit depending on what you WOULD HAVE done.

Fore instance: say you have a range of 100~200. That is your finite range. Now, you have the crit values of 20% and 50% for min and max respectively. You also use a skill that does exactly 100% damage normally. If you do an attack that would have done 100, with crit it would turn to 120% of 100, meaning 120. Likewise, if you would have done 200, 150% of 200 is 300 damage.

What if you would do something that is half way, say 150 damage? That is exactly half way between maximum and minimum. Exactly half way bewteen 20% and 50% is 35%. So, you would do 135% of 150 damage, culminating in 202.5 damage.

So, the possible formula could be: {[(Maxcrit-Mincrit)*(X-MinDam)/(MaxDam-MinDam)]+Mincrit+Skill%}*X Whereas X is the damage you would have done without a skill or crit.

Edit: Lets put the formula to use. Using the exact example I said before.
{[(50%-20%)*(150-100)/(200-100)]+20%+100%}*150
{[(30%)*(50/100)]+20%+100%}*150 This gets the ratio to determine where in the range you are.
{15%+20%+100%}*150
202.5
