Yep , sometimes the dots you make to mark the spots are bigger than the difference ebtween the spot lenghs if its a gradual taper.
In reality , the whole thing should not be done in units of inches or mm. it should all be done in thread diameters since being able to get the right number of threads in to fill the patterns at both ends is why you do it.
