Your question is poorly formed because the basis of my comment was asking how you defined "work" in the context of waterboarding. You didn't provide any sort of definition, you just said "Well, maybe it worked for other people".

But if it doesn't work reliably, for whatever "work" means, then it doesn't matter if it's successful sometimes and unsuccessful other times because if you don't have a way to distinguish the success from the failure, it's impossible to measure.

That's why I asked you to clarify what you mean when you say it might "work".
