Near zero. (A priori the W selection should not interfere with the spin measurements unless you change the "goal" with the suicide machine). Perhaps you are linking the experience by testing me on the WM after linking your decision on the spin measurements. In that case I would say the probability you found 1000 times spin up would be great, but only by pure Bayesian reasoning (not linked to the duplication indeterminacy). Bruno
