I get the metaphor.. I guess I was looking for more of a precise explanation of what happens in that jittery moment as far as the machine itself....why does it work fine, then jitter, then work fine again. its liek the cabbages line up for a bit then don't... or there is a buffer in there helping out that can only help sooo much or sumthin. Guess I am not explaining myself well. I get that they are different rates and all. I guess I figure if anything this would cause it not to work at all... not the work90 percent of the time.. then not.. then work again thing.
