Redis [QUESTION] redis bloom filter auto-scale

Question: I use bloom filters to store many items. As the number of items increases, the bloom filter will expand by creating sub-filters. I found that these newly created subfilters had half the error rate of the previous subfilter. Can I specify that the error rate of the newly created sub-filter is the same as the original one? Why does the newly created sub-filter have half the error rate of the original one?

I used the bf.debug command to observe the situation of this Bloom filter
