What a foolish question. That is clearly NOT false advertising. It does not say one of EVERY four wins, rather 1 out of 4 wins. I am more like 1 out of 3 on winners, so you are just unlucky in addition to being foolish.
I am not your lawyer and you are not my client. Free advice here is without recourse and any reliance thereupon is at your sole risk. This is done without compensation as a free public service. I am licensed in IL, MO, TX and I am a Reg. Pat. Atty. so advice in any other jurisdiction is strictly general advice and should be confirmed with an attorney licensed in that jurisdiction.
