I'm looking for the numbers of people who flew stunt at the Nats over the past fifteen years or so, particularly in Advanced. AMA has data, but it's flaky. I think a good metric is the number of people who showed up intending to fly, hence got assigned flight numbers for qualification flights. Probably the best source would be scoreboard pictures. I have numbers for 2005, 2008, and 2010 through 2013. Curiously, I don't know how many flew Advanced this year. AMA says 8, but that's not right. Please post or send me scoreboard pictures or official data. Thanks.
