ADS-C and Indicated versus True Mach

I haven't used ADS-C yet on our EASy II equipped falcon, however I have looked up the difference between true mach and indicated mach in the relevant performance section. For a True Mach of .80, the pitot static calibration curve show this to be an Indicated Mach of .813

So I'm expecting to fly at .813 indicated, when assigned a true Mach of .80

And I'm expecting .813 to be sent via ADS-C, would that be correct?

And if so, how much of a mach variance does it take before oceanic control gets concerned? In this case it would be Mach .013

However, the mach correction gets even larger as the mach increases above .80 true

Thoughts?
