This is a very helpful piece of information I overlooked.

I got two theories. First is the the rotor tip is wide that much and is a mechanical limit.
Second is the soft theory. The degrees between falling edge of the widest low res slot and the rising edge of the next low res slot is exactly 46 degrees, It could be coincidence, but as we know in the code PCM counts high res slot between falling edge and rising edge of low res signal and determines current firing cyl ID.
So we know this? Cool.

I would venture a guess that this is because the sequenced slots differ in 5 degree steps (plus 2 degree base), and that more than 4 degrees of error would prevent the code from determining cyl ID.
