Klein doesn't use the "classic" formula. They preferred another RGBW luminance balance which won't give you perfect white luminance. So red luminance might be back into tolerance but white will not be as accurate as with the classic formula.
I already created some Excel spreadsheets by the way, one of them applies TMC to profile created in LightSpace. If you are interested, write me a PM.
