How the #### can you measure that!?
For ham use, there is no real reason to have a super accurate frequency readout. I would be suspicious of anyone who thinks their dial readout is accurate, especially on SSB. Even on CW, the difference in what tone people prefer can cause a few tens of Hz apparent difference between readout comparisons.
The only real way to tell what frequency is indicated is to zero-beat a CW signal. Since SSB doesn't have a carrier, that won't work. Also the audio of most rigs filters out the low frequencies, so as you get to zero-beat you lose the audio and can never quite tell, certainly not down to a Hz or 2.
Personally I wouldn't worry about the difference. Let the observers think they are accurate. It's their dellusion.
