If fortune telling is too much, is it not allowed?

A fortune teller's fortune telling is like doing a math problem. There is a formula. Accuracy depends on the professional level of fortune tellers. If a fortune teller with the same level does calculations for the same person, the calculated results may be similar. Therefore, calculating different results can only explain the level of fortune tellers. Too much is not inaccurate. Too many are inaccurate, and then no one can be accurate.
