Back in my CFI days I would regularly indicate P, as in airsPeed . I am not sure what my backwards GS was though.

Don't know how many of you fellas have ever tried back in the instructing days or there-abouts, taking off and landing without ever leaving the runway centerline(usually in a 150-152).

For those of you who don't have a clue what I'm talking about...........Need a STRONG headwind day, preferably right down the pipe.......then rotate, SLOW flight and come backwards down the runway and put her right on the numbers where you left just seconds before. It can be done!!! I've seen it and have the pleasure of doing it once myself. Anyone else?
