Hi.
I understand what you mean Terry.
Having read my fair share of journals and books over the years it's often found that's what written and what's done in reality are two separate entities.
A recent restoration on a European radio had the oddest AVC circuit, it used a single diode detector but the resultant DC was fed to a triode valve that varied the RF and IF valves cathode voltage! The set was complex but also skimped on other parts of the design. My Tandberg also only uses one diode for detection and AVC.
