You apparently don't understand how a FAA TRACON is organized. It's not worth the banter
I’m a former GS2152, if you know as much about ATC as you think, you won’t have to google it. HT’s understanding wrt to how a supervisor oversees the area is correct. I respect your knowledge of TERPS, at times reading your web site. That doesnt translate to the nuances of the ATC system. I won’t belabor the point, but if you’re going to continue down this path, go find an active controller at SCT and ask them how it works. There’s a number of them on prune.
