The beautiful part is that we have the term transonic to capture speeds in between Mach 0.9 to Mach 1.1.True but then people would bring up issues with Supersonic stuff, as that's Mach 1.1 instead of Mach 1.000000001 or similar.
Also I remember a sonic boom speed has been calculated so no need to estimate.
The imperfect part is that we do not have similar measures for speed of light.
So when one can tag light movement one is blindly assigned 1.1 c instead of actually calculating the yield.
