can probability be set the same in random strategy?

[hheavenknowss]

Hi there, wonderful work. I have an question about random strategy, can I set the probability same in this model? like [0.2, 0.2, 0.6, 0.6, 0.8, 1]? I have read code in the quantization_scheduler.py, and in line 116:
else: probability = (self.iterative_steps[self.idx] - self.iterative_steps[self.idx - 1]) / (1 - self.iterative_steps[self.idx - 1])
I think that means NO, but I have set the probability above, and the results not bad. I wonder what really happen here. can you help me plz?
