How to calculate Shining Cross damage?

*THIS IS JUST A FUN EXPERIMENT* (Against DON'T YEETi lv103 physical resist 4%)
These stats are from Coryn's stat calculator
2142 ATK
2231 Sub-weapon ATK
CR 100%
CDMG 273%
SRD 109%
STAB 100%

AND from the DW CALCULATIONS
I get (rounded)
Main ATK = 942
Sub Weapon ATK =330
Sub ATK = 1010
Sub Base Damage = 1053
Subhand Stability = 65
Dual Swords Skill Base Damage = 66682

More things to boost damage
-Fire Element Anniv IX 1hs
-Storm Reaper 10 or Smite on Shining Cross
-Cross Parry 10
-Kairiki Ranshin 10
-Warcry 10
-Power Candy
-Food buff
-ATK 58 , Weapon ATK 58 , STR 10 , %5 stronger against Earth , AGI 10
-Barmbrack

3 + (0.1 * 10skill level) + ((0dex + 255str + 220agi)/5)/100 (Stat from gears not included); multiplier for each hit
100 + 20 * 10skill level; constant for each hit (idk how to calculate these multipliers and constants help)

Please help me with combo - dont need to think survivability and mana too much since we're just against DON'T YEETi - also have 2k mp and 64 ampr
-Opener skills i got are sc itself,storm reaper,reflex,impact,spinning slash,twin slash,cross parry,shadowstep,kairiki,decoy and backstep
-Ender are mostly same except finale lv1
-my combo would be
-spinning slash > sc smite > finale smite
-reflex > decoy swift > cross parry consecutive
(thats all sorry for being so dissapointing)

Proration are maintained by atleast 3 autos before and after a combo

 

The yellow is such a bad color choice. People who wouldn't bother marking that, would think that you wanted a combo rather than the calculation.

 

I tried to hide that but I guess that'd confuse people like what u said so I'll change it

 

How do you have so much mp?

 

why not shadow step>sc (smite)>backstep(conc)/ finale (smite)
