@HalcyonJAC Calculations all look good now :-) Just one thing: we don't need the % Change from previous column on the Applied tab. Is it possible to hide that column on the Applied tab only? Make the test white, would that be a quick solution?

@nickaddy The % Change from previous column has been hidden on the Applied tab. Could you test it again, please?

Looks great, @HalcyonJAC thx!
