10 days ago I got a new one and the median went to zero (0) each and every single day. The original frame never registered a zero ever and now all of the sudden, every day is a zero.
Don't get me wrong, I am still chasing leaks when I am fast asleep or tossing and turning. The 90% leak rate also appears to come down but without a long daily data gathering project, I cannot quantify the numbers. The .cvs file does not contain leak statistics.
I do not think this has much effect on my therapy, but it was a real eye opener. Any else find differences in "identical" masks?
