The 3/4 scale deflection tolerance is only for tracking a VOR or ILS;
passing over a VOR will almost always get full scale deflection in the cone
of confusion.

He correctly points out that the
standards call out 3/4 deflection as max deflection, and there seems to
be nothing to account for this type of thing. So, is this (passing
directly, I mean directly, over the navaid) a skill that I really should
have down by the time of the checkride? Just looking for a 2nd (and
possibly 3rd-150th) opinion here.
