Hello! Could anyone help verify the validity of this stat calculation formula please?

Formula:

(
    (
        (base stat)
        * (100% + awakening percentage + skill tree percentage if any)

        + (awakening flat + skill tree flat)
    )
    * (100% + equipment main stat percentage + equipment sub stat percentage + equipment set percentage)
)
+ (equipment main stat flat + equipment sub stat flat)

Simplified:

Take base stat, then add & multiply effects of awakening/skill tree, then multiply effects of equipment/set matches, then add effects of equipment

Thanks!
