>To eliminate the most obvious bias (1v5 coin), until all that could had been left was incidental? There is only one coin, flipped _twice_; not a running occurrence, but in couples, perfectly simulating two coins functionally. Once a literal couple of coins result in a XOR'd result eventually, no matter how biased - they differ - the exact ordinality of which will be random. Two sides to a coin, no matter how random, still half the chance. (for lurkers cringing at my subtle mis-understanding)
