Very well done and such an excellent trick! I love it. One little idea I use is to utilize the 22 cards leftover as 2 of the predictions. I count off 6 cards, put the leftover 16 in the box, then put the 6 under the box without mentioning it at all. If I end at 6 or 16, I say, at the beginning I put some cards in the box, let's count those. Or, at the beginning I put a few cards under the box, let's count those, etc. It works well for me and my style. Keep up the great work. Also, if the values of the 6 cards add up to 26, you have all 3 outs with no written prediction.
