I challenge you to articulate your argument better! The percent change is not part of the equation! The tank is not compressible so the pressure does not change with depth! The SAC takes the volume of gas you are breathing divided by the ambient pressure, and does not relate to a change from the last sample time!
My guess would be that it has to do more with their algorithm than reality! I would guess that their sample rate is higher than your respiratory rate! So they use many many samples to calculate your breathing with a weighted average! However, that would drive your readout low so they compensate with a false backloaded history in the model!
All this speculation of mine though should be prefaced with this, I can't really see the graph well on my phone!
