Dear Helmut,

❝ now I’m confused.

I think all the confusion comes from that sigma_w, sigma_d, sigma_delta values including their estimates
which are used by all the authors cited within this thread in a different meaning.

I'm not able to figure out who is who, what is what. Sorry.

The only thing I'm convinced of is that your formula (2) above is correct.
If you write the confidence interval for the BE decision as
PE(T-R) +- SD_(d)*tval(0.95, df)

The rest of your algebra is straight forward.
And correct if you ask me ;-)

.

BTW: the formula (2) is not the error term in the 2×2×2 crossover.

Detlew
