It is definitely the the gear spacing for the ratios. The internal gearing is 0.75, 1.00, and 1.33. If you want to use a double chain ring the spacing is 4 teeth (40/44T) for half step gearing or 10 teeth (40/50T) for the step and a half gearing. The idea is to get even spacing when plotting the gear-inch ratios on the natural log scale or a even percent increase progression.
