That's right, my mistake. That makes a bit more sense than what I was saying.
So what is that, 2 contact patches? Since after each crank revolution, the tire returns to the same spot (after turning three times), that means that the power stroke (or leg-lock. I noticed after my previous post that we were talking about skids, not just pedaling) will always occur on the same two spots on the wheel.
Then how does the rule work? This might be more or a mathematics problem than a cycling problem, at this point. Do you multiply the first number in the ratio by 2? So 46/18 = 9:23, so there are 18 possible contact patches?
Clearly, at this point, I have no clue.
