For a 5-speed, 13-17 or 14-18 would indeed qualify. For a 7-speed, yes, 13-19 or 14-20.
How about for a 9-speed? By the same single tooth progression logic, 13-21 would qualify, would it not?
My definition: TL-TH = N-1, where TL = low/large cog tooth count, TH = high/small cog tooth count, and N = number of cogs on the cluster/cassette.
