If your track ends are long enough, you can get away with a lot more than that. I once rode my Fort to a hill climb on 42/16 and turned the wheel round to 42/21 for the race and that was well within the available scope. Some track frames have very long ends, but 1" of axle movement is enough to accommodate 8 teeth difference.
