Did anyone tune the TCS by the chart in the first place? Maybe you used the chart for starting settings and then tuned the transmitter for max antenna current but if you just used the charts and ignored the antenna current meter and the plate current meter why did they install them in the first place?
The question I would have is was the radio set up by a technician on the crystals that were installed with the readings written down on the front cards and the crews of the boats were told to set the radio up according to the chart that way or were users of the radio instructed on how to tune the transmitter? Or perhaps back at the dock a tech set the radio on one channel and everyone was told just use that set up channel and don't touch the radio?
I know it antidotal at best but both of the great grandsons of the TCS the Sunair GSB-800 and the Harris URC-94 have huge stickers on top of the radios that have the operating instructions written for idiots but they do tell you how to change the frequency and tune the antenna.
In the old days of HF AM marine radio all the transceivers they had for small boats had no provision for any transmitter adjustments for the user, the loading coils and everything was installed in the radio with no user access. My understanding then was that you had to have at least a second class license to set up or tune one of those old HF AM transceivers.
