Heres an idea ...
why not use the same technique as used on nearly ALL car ignition pickups on
modern software-driven ignition systems ..
typically you have a say, 30 tooth wheel and a pickup .. and for the index
mark, simply a missing tooth.
thsi saves all the problems with spacing the extra-wide indes pulse in your
scheme ( you havent explained whther this extra-wide slot should start in the
same place as a normal slot or be centered etc this leaves room for error)
... a series of equally spaced slots with a missing slot for the index is
much to describe and less prone to intepretation by the users in odd ways ...
