Dick, the chart was just a chart. It didn't enable anything and didn't require education material to use. "Appropriate ATC frequency" can be defined however you want, be it as shown by FIA boundaries on a chart or by using "biscuits" to locate the closet VHF outlet on a chart.
As I've said every time you've trotted out the "honest real name", I'm just a controller with no particular influence on aviation matters. Knowing my name would offer you no extra insight.
Yes, it was me.
