Pretty much, yes.So does that mean that after your damage calculation with resistance, you do that damage as a maximum and up to 20% less damage?Oh also the standard deviation of damage numbers is 20% of the damage inflicted This is a constant!!! (scientists get really excited when they find a constant)
this is probably indicitive that damage is set to "moderate randomness"
This means that 68% of the time you will hit within 20% of your max damage.
1 standard deviation is 68%
2 standard deviations is 95%
So 95% of the time you will hit a training dummy within 40% of your maximum damage.
Make sense?
Someone can verify this easily by hitting a dummy 50 times, recording your listed damage and the damage of each hit.
Average all the numbers using the =average(#1,#2,#3...) function in exel and find the standard deviation using the =stdev(#1,#2,#3...) function in exel.
Your average should be 10% below your max and the standard deviation divided by the average should be 0.2 (20%).
