This caught my attention - one litre per hour is a really really  
small number in
terms of air flow for any zone bigger than the box an ipod came in.   
This would
be held as an equivalent m^3/s which is at the 4th decimal place and
the 0.5 litre per hour might be at the 5th decimal place so it might
be possible that simple rounding errors and numerical noise are factors.

And a change in volume in a zone could easily result in a bigger
flow than this fixed rate.  Suggest a run with 10 litres per hour etc.
to see if the glitch goes away.
