first card values

Now I understand what you want to do. The correct way is the one you used in the example but you could use the following system:
-4 1 1 2 2 2 0 0 0 -1 (from A to T) which would give you a correlation of 0.95.
Hi-Lo can also be used but the correlation would be lower: 0.82

Hope this helps.

Thanks so much!
