I did it a few months ago while I was still looking for a new bike and it seemed pretty right on. My problem is having a long reach. I was really hunched over and uncomfortable on my last bike and the Wrench Science guide gave me a good idea of what top tube and stem length to look for. I got a Bianchi Volpe, so not a track bike. I don't know what adjustments you'd need to make to the numbers for a track frame.
