This is the question now.
Please tell me if anybody ever mentioned this or tell me if you think that this is not that important but you have to explain the reason as well.
This I believe is the most important thing somebody must first do when he wants to test an LRL no matter what test-protocol he is going to follow.
Well sorry, I haven't seen anybody doing it yet.
Well, as far as I know.
P.S. Just keep in mind that I am always talking about the majority of people and that there are always exceptions as in anything in life.

Part of the requirements of testing in a controlled environment requires that there be a Pre-test and a Post-test using a target in plain sight, which of course the LRL is supposed to be able to locate.
The confines of the test area should be searched for possible targets, but NOT with the LRL itself. Naturally, any possible targets should be removed from the test area that might interfere with the LRL.
If the Pre-test is successful, then one can go ahead with the Real-test, which should be of a double-blind protocol. Following the Real-test, you then perform a Post-test. If the Post-test is successful, then you can be
reasonably sure the results of the Real-test are valid and significant.
If you need more details, please see Carl's dissertation on testing LRLs under double-blind conditions.
