Pendulum Testing for Guidance/Intuition

[JackOfHearts]

I write the nine number on paper, I ask if the first number is between 1 and 5. Until I find the whole number.

In the case of 255*78, you ask if number first '1'9890 is between 1 and 5. If it's yes it's ok then you keep going. Ask if it is between 1 and 3. You keep going until you find a number and then you check if it's right or not.

I think there is some more advanced method to do that but I don't know yet about them.

Pendulum left to right is yes for me.
