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.
