The calculations for effective health increase are incorrect.

The author claims that 1 AR effectively adds 1% of base HP, but this is not true.

For example, 10 AR = 9.09% damage reduction. For a 1000 HP hero that means a 1000 dmg attack would actually do 909.1 dmg, which means the hero would effectively have 90.9 more HP which after rounding would be 1091 HP.

1% of 1000 = 10 EHP = effective HP DR = damage reduction AR = effective armor

0AR = 0.00% DR => 1000 EHP 1AR = 0.01% DR => 1001 EHP (+1 EHP vs 0AR = +0.1% of base HP) 10AR = 9.09% DR => 1091 EHP (+9.1% of base HP) 11 AR = 9.91% DR => 1099 EHP (+8 EHP vs 10AR = +9.9% base HP = +0.8% vs 10AR) 12 AR = 10.71% DR => 1107 EHP (+8 EHP vs 11AR = +10.7% base HP = +0.8% vs 11AR)

50AR = 33.33% DR => 1333 EHP (+33.3% base HP) 51AR = 33.77% DR => 1338 EHP (+5 EHP vs 50AR = +33.8% base HP = +0.5% vs 50AR) 52AR = 34.21% DR => 1342 EHP (+4 EHP vs 51AR = +34.2% base HP = +0.4% vs 51AR)

200AR = 66.66% DR = 1667 EHP (66.6% base HP) 201AR = 66.78% DR = 1668 EHP (+1 EHP vs 200AR = 66.8% base HP = +0.2% vs 200AR)
