Well, also realize that graph doesn't have error bars on it, and is 12
hour rolling averaging. So if you end up with only 5 changes in 12 hours
going through, and 1 fails it's going to hit 20%. It's actually a
totally non ideal way to handle this data, but it's about as good as you
can get with graphite.
