If anyone needs data files for testing, just ask me! I have data 
available from nearly all models supported by libdivecomputer.

[Note that many of those memory dumps contain personal information (like 
home addresses, telephone numbers and so on), so unfortunately I can't 
really make the data publicly available. But I can provide access to 
developers on request.]

Anyway, more data is always welcome! Especially when some of the less 
common features are used, like multiple gasmixes, multiple pressure 
transmitters, gauge/freedive mode, SCR/CCR dives etc. The more data we 
have, the better we can avoid regressions in libdivecomputer...

If you look carefully, you can notice gaschange events in smarttrak. On 
the graph there is a line that represents the MOD. A change there is an 
indication for a gas change. Unless the change in oxygen content is 
really small :-)

But you're right, in general events are not visualized very well in 
smarttrak. That makes them rather difficult to reverse engineer.
