If multiplying two negatives equals a positve then shouldn't two Bedieveds equal a Lechatehila?
E.G. I heard from a HaRav Mansour Shelit"a that if one washes one's self with Tisha Kabin, then it counts for Mikwe Bediavad + HaRav Musafi Shelit"a writes in his book Shivat Sion that if one washes their hands with a Natlan 40 times (20 each) it counts as if one has Toveled in a Mikwe.
Do two Bediavads equal a Lechatehila?
