It is not necessarily true that your skid spots will double. They number of spots will remain constant depending on what ratio you choose. It can be argued that each the intensity of each patch will increase but the overall number will not necessarily.
It doesn't matter because with one foot your repetitions are every 2*pi Rad and with two feet they're every pi Rad, but you can "fit" the pi Rad into the 2*pi Rad, they just happen with twice the intensity.
