Just as a rough guide: what are the minimum and maximum numbers of offers a Black-tier woman in Tokyo might receive during her first six months after registering?

There was a Black-tier girl who quit after six months, but in that time she went on dates with four men and had an adult relationship with one of them (just once, after which he stopped contacting her). She said the other encounters weren’t good either—some men tried to forcefully take her somewhere from the very first meeting, while others barely spoke. She’s young, extremely beautiful—model-level—and well-mannered. For someone in the Black class, is that about the usual number of dates and results? There’s also a possibility that she received dozens of offers but couldn’t make the schedules work.
