I also discovered a nice trick from my instructor, to request
"delaying vector". If you find you are tired, falling behind or need
to get reorganized, you ask for that, and relax and get prepared again.
After an hour of actual approaches, you can get pretty tired.

I haven't heard of doing that, but it sounds like a great thing to
remember! I recall being vectored waayyyyy out on occaision, for some
unknown reason. It was always a great chance to relax, reorganize and
prepare for the next approach. Thanks for the tip!
