Would it make sense to cross an NDB 3 times in the completion of an

I'm thinking where there is a hold in lieu of a PT, you may cross the
NDB, complete a parallel hold entry, cross the NDB a second time, then
do a racetrack with timing and descent, then cross a third time as the
FAF.... Normal ops?

Once you've made the hold entry and are inbound at the fix, you've
completed the hold. You don't need to go around again.
