Maybe I've just seen way too many random sequences, but I was able to hold it around 40% for a while. True randomness tends to generate sequences that are slightly "uncomfortable" or "inhuman" -- I can't think of a better way to describe it. So I just kept trying to generate the least-comfortable sequences I could think of, and it worked alright. There should be a lot more long runs than you'd imagine.
