I like the idea of the trick. I like the construction of the trick.
As a magician there
are 2 steps to figuring out the number.
Step 1 was easy to master.
I have spend
close to 90 min practicing step 2. And when I say practice I me just trying to get the number
right, not doing the full patter. So I can do 4 or 5 numbers a minute.
I am still only
about 60% accurate, which is little better than a guess. 4/3 works for me but getting the 1/2/5/6
feels like I am just guessing.
Method 1 (in hand) is not something I can get to work at
all.
Method 2 (on a flat surface) only work for 1/6 on a hard flat surface. Will not work
on a pad or even a table cloth.
