Singer is a proven liar. Remember his claims that he both lives in Carefree and doesn't live in Carefree. Not to mention the 100s of other lies he's been caught at. Nothing he has ever said can be trusted. Hence, the claim "A guy goes from a loser to a winner after tons of research" is nothing but hearsay and most likely pure fiction. No court in the world would accept this kind of hearsay as evidence. Why would any reasonably intelligent person accept something no court would even consider? The answer is that none would.
OTOH, Dancer has mathematical PROOF that the system he teaches is valid.
IOW, we're talking night and day between Singer and Dancer.
