We don't need even spaced gears, we don't need any gears (well maybe at least one). We want the "right" gear most all the time though. Having gears in steps that mimic what our bodies like is the goal. Lot's of opinion and, likely research, suggests that 10 to 15% of ratio change between gears works well for many.
But you do live in the USA where it's your right to have any gearing spacings that you like. Andy
