Comment:
I think you are right. I forgot that the Nemo Air uses 5 bytes per sample instead of 2. Those extra 3 bytes may indeed contain tank pressure data.
Initial investigation shows that one of those bytes contains the gas consumption (in l/min) for each sample. That's most likely the value used to plot the graph you attached. So far I have not been able to find the tank pressure per sample, only the begin/end values. I could find the values corresponding to the <tankpressure> elements in the uddf. But if I treat those as delta values, then the pressure drops too fast, and I end up with negative pressures. That's certainly not correct. \ \ \
