Review comment:
       is calculating the histogram reliable in how long it takes? Does it take 
longer as we get more data? I could see how we'd account for it if it always 
takes the same amount of time, but a variable time doesn't seem possible to 
account for. I don't think we can assume that the relative performance impact 
would be the same between runs
