(In reply to re: Leading answer (spoiler)

The way I interpreted it, it didn't matter about leading zeros, as you are certain to have some digit first, and without leading zeros the first expected lenght involved is just 9/9 instead of 10/10, but from then on it's still 10/9, etc. as now, whether the first digit was a zero or a guaranteed non-zero, it's still the same.
