Its actually the transition from low to high if memory serves me correct (or vice versa). There is a pattern used, there is more than one tooth/space whatever that application used. The holes or teeth depending on manual/auto application. I believe that system used 4 even markings for one cylinder and a larger gap and three markings so the PCM can detrmine which cylinder is coming up based on the larger gap and the cam sensor input.
