@RockyRoer: for you the solution code is (R2C2 * R9C92 * VarPop(L6R1) * 333337 + VarPop(L8)) * VarPop(L7)
Solution code: Column 5

For future solvers, its variance of a population and not of a sample, so don’t use n-1 like I did. Once I realized my mistake, I could disambiguate the coloring and it flowed smoothly.

You're right, I should have made that clear. Adjusted formula now.

That‘s a nice looking puzzle with an elegant ruleset and a solve path that remains tricky quite far along. Thanks for sharing.
