Indeed.

@Dan: Can you send me a memory dump of your dive computer. Simply enable 
both the libdivecomputer dumpfile and logfile checkboxes in the 
subsurface download dialog. Note that it will help if you can record a 
dive with all gas mixes set to different values (e.g. 22%, 23% and so 
on). Air gets recorded as a zero byte, and since there are many zero 
bytes present in the dive header, it's difficult to tell which byte(s) 
are the gas mixes.
