| In this fight I was wearing Cape of arcane protection, Light mithril coif and Light mithril boots.  Total magic proof 25% but I only had 23% magic proof.

| Because you did the math wrong. 
 5% + 5% + 15%
 
 You should have done it this way:
 
 (1-0.05) * (1-0.05) * (1-0.15) = 0.767125
 
 This means you getting 23.3% magic proof.  To make it easier to understand for example you have two 50% magic proof arts, but instead of 100% magic proof, you get 50% for your first art, then 50% of the remaining 50% is 25%.

| It's calculated as 1-(100-15)%(100-5)5(100-5)5 = 1-76.7% ~ 23% | 
| ah Shift didn't work :/ 
 It's calculated as 1-(100-15)%(100-5)%(100-5)% = 1-76.7% ~ 23%
