Resmed S9 Leak Rate stats

Resmed S9 Leak Rate stats
I've noticed that wherever leak statistics are reported (both the Daily page, and the Statistics page), the numbers  always occur in multiples of 1.2.  For example 1.2, 2.4, 3.6, etc.  I've seen this both in Sleepyhead and OSCAR.  Does anyone know if this is due to the machine?  Real world data shouldn't behave like this.

Thanks

Update . . .
I've scanned a number of day's leak charts and never found any non-zero value that wasn't a multiple of 1.2.  I also viewed a good number of Airsense 10 posted charts, and this appears to be similar for the Airsense 10 machines.  It seems that the Leak rate resolution is 1.2 l/min for Resmed.   I'll be interested if anyone can show that this is not true.

RE: Resmed S9 Leak Rate stats
Based on the range and resolution given in the PLD.edf files, you are exactly right.
Signal     4
Label      >Leak.2s         <
Transducer >                                                                                <
Units      >L/s     <
Min        >0.000000<
Max        >2.000000<
Dmin       >0<
Dmax       >100<

2 L/sec max, with a resolution of 0.02 L/sec gives a resolution of 1.2 L/min, and a max of 120 L/min.
