Exactly. the teeth actually slant towards the bar so as they are sharpened
the cutting edge is closer to the bar and the depth guages can become
higher than the cutting edge resulting in polish rather than cut. On the
other hand a depth guage too low can be 'grabby' and lead to increased
kickback.

Which is another good reason to keep your teeth close to even length.
Avoids hit and miss and the strain that causes.

They make two dollar gages for filing the rakers, just give a couple of
front-end rounding passes after filing for depth, which is gaged from the
tooth to come.
