Guilty. I wanted to be up-front about the constant factor of 1 or 2. I was tired when I wrote that and was actually looking at cleaning that up a couple days ago, but got distracted. Soon.

To further clarify, if a Bloom filter query is O(K) where k is the number of hash functions, then when k=7, the filter could be described as O(1).

The constant factors here are important for practical use. Hashing 7 times is significantly different than hashing 1 or 2 times.

For the original commenter, give me a suggestion if you don't mind. How would you expect to see that info depicted in a comparison chart so that it's honest and obvious?
