So i've been using the FP 432 for many months, and lately tried the F20. I am particularily interested in the leak performance of each mask when used on my face.
YMMV
Here are the OSCAR results after 7 days with the F20 mask:
The % time above threshold (25l/m) is easy to validate: The number of minutes at > 25 l/min divided by the total number of minutes of the sleep session.
As far as the "95% leak rate" that a bit more convoluted, and frankly (as Pugsy has pointed out in her thread) may not tell a complete story.
The last piece is the "Average leak Rate" for each sleep session. The problem there is that if the leak data is skewed, the "average" can be misleading. So how could the LR data become skewed?
That leads me to ask the question: How frequently is the leak rate calculation performed?
