OSCAR [av. leak rate vs. 95% leak rate question]

OSCAR [av. leak rate vs. 95% leak rate question]
Hello,

What is the difference between "Average Leak Rate", "95 % Leak Rate", and " Percentage of time above Leak Rate threshold"?  Is the leak rate threshold 25 L/min?

Thanks,

Rick

RE: OSCAR
Average leak rate is just that, an Average
95% Leakrate is the Leak rated where 95% of all values are at or below that value. It is a specific statistical value.
Percentage of time above Leak Rate Threshold is the percentage of time you are having a leak rate that actually impeads the function of your machine. which is just under 25 l/m

RE: OSCAR
Even though the values are labeled with a percent symbol, they are actually Median, 95 percentile, and the Max as actually 99 percentile. The reason the Max column uses a 99 percentile is to remove artifacts that would skew the real data. The default leak rate is 24.0 L/min. This value can be modified in the preferences.
