Heh, well I did give it a go again. I wrote down what my results were and they are as follows -
1. 5 cards left to turn over
2. 26 left
3. 43 left
4. 26 left
5. 5 left
6. 36 left
7. 22 left, though on the last lot of 7 I turned over, I was feeling unconfident about whether the card was near the bottom or not.
8. 45 left but again, I was feeling unconfident about the choice I made of when to stop shuffling and start turning.
9. 43 left
10. 32 left
11. 36 left
12. 50 left
13. 35 left
Then I changed the way I was thinking from trying to feel whether the card was near the bottom to trying to push it here AND feel whether I was succeeding.
14. My card was the 10th I turned over
15. Mine was the 3rd
16. Mine was the 13th
17. Mine was the 5th
18. Mine was the 16th
Make of it what you will. Maybe I'll try again later.
What kinds of results have others been getting?
