All the machine does is measure how quickly you go through the first X degrees (where there are ticks book-ending that range) and then it infers, basically approximates, how far it thinks it will go total.

yeah so from what I understand the sounds with in the tick allows the timegrapher to measure the velocity of the wheel at that point in time and therefore estimate the amplitude.
If there was only one isolateable sound per tick it would be impossible for the timegrapher to estimate amplitude.
