Hope this is interesting and adds to the discusion:-

While some devices do calculate the tempo *and* use it, many do not.

What they do is simply "count clocks" and use that as a time base.

If there were only 2 clocks per beat then swing would work easy enough.
...but trying to sort out the timing for 24 ticks ( or whatever the actual figure is)
to produce a swing in the slave machine 12 of those ticks would have to
be drawn out, and the other 12 sent quicker to compensate.

Generally getting the BPM from midi clock just isn't accurate enough
for syncing.

What does it do between the 2 different 'tempos' Smoothly change tempo from one to another It can't do this until it's receives the next clock pulse. If the incoming clock move smoothly between the 2 'tempos' it'll swing everything, not just the offbeats. How would you shuffle just the 8th notes but not 16ths - can't be done with a simple clock.
