Studying mob damage Post-BB

Here's what I've come up with so far:

This is what happens if a mob damages you

ORDER OF EVENTS:

• Check if the mob missed the attack. If so, return 0 damage.
  
• The mob's attack is fetched
  
• If the mob is affected by Threaten, reduce it's WATK value by the percentage given in the skill OR if a mob is influenced by a damage increasing skill, increase the WATK. Precedence is on Threaten.
  
• Bounds checking - If WATK is less than 0, WATK = 0. If WATK is greater than 30000, WATK = 30000
  
• Calculate mob base damage
  • MobMin = mobAttack * 0.85
    
  • MobMax = mobAttack
    
  • return (MobMin - MobMax) * MobMin * 0.000000100000010000001 + MobMax;
• Calculate Player BasePDD (see spoiler #1)

The above bolded is dangerously close to being 1/9,999,999

This is about as far as I've gotten in about 1 hour. X_X

 #1 - Calc_Base_PDD

Code:

signed __int64 __thiscall BasicStat__CalcBasePDD(int this)
{
  int v2; // esi@1
  signed int v3; // ST24_4@1
  signed int v4; // ST28_4@1
  signed int v5; // ST2C_4@1

  v2 = this;
  v3 = _ZtlSecureFuse((this + 36), *(this + 44));
  v4 = _ZtlSecureFuse((v2 + 48), *(v2 + 56));
  v5 = _ZtlSecureFuse((v2 + 72), *(v2 + 80));
  return (_ZtlSecureFuse((v2 + 60), *(v2 + 68)) * 0.4 + (v5 + v4) * 0.5 + v3 * 1.2);
}
