I thought this would be entertaining lol. Lets here what the worst advice you have been giving during contest prep. Maybe this is something you even implemented and disaster stuck. I think peak weak is where we will hear the craziest protocols.
I've been lucky to have good guidance and even things I tried were from reputable sources. However, I had my run in with some crazy advice prepping for my second show. I ran into a guy at the gym and he claimed he was a "natural" pro and had his masters in nutrition....hmm maybe he understands the body. Let me tell you you can have education and had competed and looked good but it doesn't mean you are doing it optimally. This guy told me for a Saturday show increase water to 3 gallons Monday, 2 gallons Tuesday, 1 Gallon Wednesday, then Thursday and Friday drink ZERO water. I had to clarify and he repeated absolutely zero water. He told me how dry he got and that he lost 20lbs. This was the most ignorant thing I ever heard. I've you are stage ready lean for most of my clients and myself I never cut water. Dehydrating yourself for 2 days is dangerous, but it would leave you looking extremely flat. Glad I can think for myself cause man that would have sucked lol.
