Its not proving you wrong matey its basically telling you how DP is worked out, the higher the dp the more efficient the mesh is, ie less energy loss between the gears due to backlash, but there comes a point when it is not really noticable, for instance if you had a ratio of 12:1 with a 48dp and the same with a 64dp you really wouldnt notice any difference in runtime, there really isn`t a large difference in the size of the teeth and they are the same shape ie straight cut gears. A well meshed 48dp gear is as good as a 64dp in my book, i never ran 64dp in tourers either and gearing is possibly more critical with them, especially in 19 turd and stock. There is also the side where the spurs we run are very rarely super true, so a 64dp would be eaten alive as soon as you landed your first big jump of the night.
