For anyone interested, here's the power graph from my 13.37s flying 200 at SSS r6 last Sunday.  It was blowing a gale, a huge norwesterly which made for a reasonably quick track (for Blackburn anyway).  I rode on a 53x15 (~96").  It's interesting to see how a flying 200 looks from the point of a power meter.  I'll keep posting this sort of stuff so you can see what these things look like.  The numbers aren't great, but I'm not exactly a great sprinter!  Far from it, but all the same the data is worth looking at.
