But if you keep turning the wheel about 65 times or more, give or take a few revolutions, you will see the chain and sprocket marks reline once every 65 times say or find the number of turns.
Yep, you got the idea alright. Now, if you offset the chain it by a single tooth, you move the entire cycle by a single tooth. What it means that every tooth will meet a particular chain roller in every 65 revolutions, over and over again, just the cycle is moved over by a tooth. Now move it over by 10 teeth, reassemble and start the cycle over and over again, just moved over by 10 teeth. It does not matter, the chain will travel over the sprocket evenly like a clockwork. Marking the chain with an attempt to put it back into the same spot on the chain just is not necessary. At least if we are talking about the motorcycle final drive chain.
