Yes, well, there's not really one rate to report for each station, since
Minstrel jumps about a bit and tries different ones.

So far I've just been looking at the figures for airtime (the first
graph in the blog post). These are the same numbers that the scheduler
uses to make scheduling decisions. It seems like the scheduler does help
somewhat, but is not perfect yet. Am definitely lacking a good ground
truth to compare against, though. Computing the expected throughput
might be possible, since minstrel does report statistics for how many
packets were transmitted at each rate. Will look into it; thanks for the
suggestion :)
