Tracks within midi files can count time between events in two ways - clock
ticks based on tempo, or linear time frames.
If a track containing the sysex data is written using linear time, changing
the tempo wont increase the delay between blocks.

The P3 firmware midi file uses a tempo based timing, and enough ticks
between each sysex block to give 100ms delay at 120bpm, so changing the
tempo will change the delay, if required.
It seems like it's easier to find an app that will play back midi files on
any given OS than .syx files, and tonight's build of P3 Tools can read a
.mid file.
So I was thinking of just uploading midi files, unless it causes anyone
problems.
