Comparison wizard

[JohnK]

I have a question on the Comparison Wizard in Weibull++ 7. When I compare two sets of data I get the probability that one set will out last another set. I would figure that if I switch the sets and got the new probability and added to the first probability that it should add up to 1. However, I don’t get this. Why?

They should in most cases (Manual bounds might skew results for example). However both solutions are calculated numerically and some convergence/round off error might be present.
