Question : Regarding Damage Calculation

Below is the formula I found for the PlayerATK

Example for Knuckle
( PlayerLVL + Weapon ATK + AGI*2 + DEX/2) * (1+ATK%/100) + flat ATK

So my question is.
1) Is below formula correct to add the Refine Rate in Player ATK ?
Formula = ( PlayerLVL + Weapon ATK * Refine Rate + AGI*2 + DEX/2) * (1+ATK%/100) + flat ATK

2) Is below formula correct to add the WeaponATK+% and WeaponATK+ ?
Formula = ( PlayerLVL + Weapon ATK + AGI*2 + DEX/2) * (1+ATK%/100) + flat ATK + ( WeaponATK * WeaponATK+%) + Weapon ATK

Full damage (physical skills) = (Base damage - DEF + Unsheathe Attack + skill constant) * XYZ
Above is the Full Damage Calculation for calculation I found, XYZ is multiplier and Damage Boost from Element, CD or etc.
1) Is the formula below correct when I slot in Physical Piece
Full damage (physical skills) = (Base damage - (DEF * (1 - PP%/100)) + Unsheathe Attack + skill constant) * XYZ

 

Full Damage (Physical Skills) = (Base Damage (for physical attacks of non-duals) - DEF + pure Unsheathe Attack [IF the skill is Unsheathe] + permanent skill) * Full Crit damage/100 [IF crit hit] * Full Item Bonus/100 * Skill Multiplier * (1 + Unsheathe Attack%/100) [IF the skill is Unsheathe] * RNG Stability/100 * Current physical Pro Rate/100 * (1 + sum of all skill modifiers/100) [IF the skill is under their influence] * (1 + Short/Long Range Damage/100 [depends on the distance to the target]) * 0.7 [IF under the Lethargy debuff] * (1 + sum of all Last Damage Modifiers) [IF under the influence of Brave Aura and/or support the applied Mana Recharge] * (1 + sum of all combo multipliers/100) [IF the skill is in a combo] * (1 – The damage reduction factor of Gems per drop/100) [IF under the influence of the gem on the drop; repeat this for each active gem] * 0.25 [IF the attack is blocked (Guard triggered)
