l/perminute readings on S9

Why only rare occasions I see median lper/min with 2.4 I understand the 95 percent it shows 18.0 max number 24.0 usually it is 0.0 for median Range 8.4-10.6
Another nite for the pressure readings If you have a range 8.4-9.4 how can the max say 10. The 95 percent is 9.3 and median 9.2 how can the max go higher than what it is set for

The L stands for Litre -- that's a volume measurement.

Pressure is not measured in liters. Pressure is measured in the cms/h2o, which is the pressure created by a column of water so and so cms high. Higher pressure will make you leak a higher volume of air, but the numbers themselves are not connected.
