You don't have one mask for all tests.

Sorry, but you are mistaken. The srand $S ensures that the same mask is built for each run.

You can change it using sommand line arg -S=nn, but so long as you use the same value for each run (1 by default) then the same mask will be generated for each test.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
