Was Stedman inevitable The answer is clearly yes, and the reason is the early focus on Doubles. In Tinntinnalogia, generating extents with plain changes is initially explored, but 'cross change peals' were considered more desirable. Even the stage name of Doubles tells us that maximising two pairs swapping was the aim. On 5 bells, cross changes (with a single place made) can only generate half the possible rows (60), and there are very few ways of doing this possible. The half hunt touch of Grandsire Doubles (bobbing alternate leads) is one, but if you want a principle so that all 5 bells do the same work, I think you only have Stedman, Carter and their reverses.
