Absolutely agreed. Now, I've read over the FAQs and Stickys thoroughly and will be diluting also, but I'm concerned about how I was told they will flunk you for a diluted or suspicious sample. Can this typically be argued, or is it a "Too bad" type of mentality typically?

Now, I have a mouthwash container that (to spare you the details) fits nicely in my tighty-whities. Does an observed test typically take place in a urinal, or a unisex bathroom with a toilet? Do they watch you from behind, or do they insist on watching "the point of origin" directly? I'm about to do some practice runs, but I feel that due to the type of container I have, I may be able to release the urine out in a believeable way even when observed. Another question is, would doing these tests with plain H2O be reliable? Meaning, is the warm up/cooldown time of urine similar if not the same to urine, or will I have to use the real deal for my preliminary practice sessions in my bathroom?
