On a serious note, while I'll tease students about doing exactly this but I don't necessarily have a problem with cockpit / flight calls with a "L / R, X Clock". As funny as it is to think about, some dude helmet-firing might benefit from the base simplicity of L/R before devoting a few more neurons to the actual clock code after he turns his head.
If they were seeing and thinking about any traffic calls, I was happy, because I saw the alternative a lot too. Critiquing the callout was later on down the road.
I realize solos to the PCola southern OLFs were common back in the day, but considering the far more numerous close calls I had there vs the northern areas, sending a solo south for bounces always made the hair on the back of my neck stand up.
