I don't expect a stack overflow though.

In my test, This works as in it does not error but it always returns
true and executes the children samplers every pass.  I am running 2.6
build 1308652.

I have a loop controller with two child IF controllers with children
samplers.  Using this script sample, they both execute each loop pass.

I do not understand your comment.

Yes I tried.  There is a 100% chance then 0% the next 99.  I want a 1%
chance every pass.

Thanks for your comments.
