Bill, did you see the same thing I did?

The photo in step four implies a clearance of 0.0015" when the real
reading is 0.001". The user took the reading between the 0.001" line and
the 0.0015" line, not between the 'zero' line and the 0.001" line.

Would be an easy mistake to make, given the different sort of ruler shown
in 'figure 4' of the factory document:
