You might be comfortable using a single significant digit for any probabilities you pull out of your ass, but Yud ‘s methods are free of experimental error. He works using Aristotelian science, working stuff out from pure reason, which brought you bangers like “men have more teeth than women”. In Yud’s case, most of his ideas are unfalsifiable to begin with, so why not have seventeen nines’ worth of certainty in them? Literally can’t be false! Not even AWS would promise these kinds of SLAs!
