To confirm the formula would be:
((1 + (Structure Bonus / 100)) * (Refining Yield Multiplier) * (1 + (Refining Skill Level * 0.03)) * (1 + (Reprocessing Efficiency Skill Level * 0.02)) * (1 + ( Ore/Ice Specific Processing Skill Level * 0.02)) * (1 + (Processing Implant Percentage / 100)) * Security Modifier)
