How many times is tarot the most accurate? From the second time, every count represents bad, so how many times is the most accurate?

In principle, for the same or similar problems, don't do divination many times in a short time.

A short time is after your last divination and before things start to change.

Tarot cards are just tools to give you some guidance or enlightenment. There is no such thing as accuracy or inaccuracy. Tarot cards have no ability to predict the future, at least within the reach of current science.
