RHC has a couple of hairpin turns so running a big gear would lose you a lot of time on slowdown/start up
Actually, I'd say 48 x 15 is a bit low for mass start races on the track, more like 47 x 14 or 48 x 14, but then you can go full speed w/o slowing down on the track. Average speed in races often exceed 30 mph on the track. I've never raced a crit on a track bike, so I have no idea what gearing would be best, but it seems like jumping out of hairpin turns in a 48 x 15 would be brutal.
