What is the ruling regarding a man who is certain of divorce but is unsure about its wording, whether he said, "You are divorced" or "You are divorced, divorced, divorced," and is uncertain about the number of divorces? And how many divorces are counted in the first case?

Whoever is certain of divorce but doubts its wording, only one divorce falls upon his wife. And whoever doubts the number of divorces, he bases it on the lesser number. If he doubts whether he divorced twice or thrice, only two divorces fall, because any amount exceeding the certain number is a doubtful divorce.
