| Sorry it didn't help.  I thought what you had been describing was that if

Although a lot of references use this description I do not believe that
it is correct.  I think the initial DIM or BRI always results in a micro
step regardless of whether it is followed without a gap by additional
commands.  See:

So the original poster's '+ X' would always be at least + 1.
