Leak Rate - Rescan vs. Sleepyhead
I download data into both Rescan and Sleepyhead. Just recently I have noticed a disparity in the max leak rate. In Rescan my leak rate is: median 0, 95% 0, max 6 and in Sleepyhead it is median 0, 95% 0, max 15. (Even an old Mirage Quattro does OK)

I just chased it down and it looks like a Rescan bug. The Leak rate graphs in both Sleepyhead and Rescan agree with the Sleepyhead max of 15. I am using an older version of Rescan 5.1.0.8731 and I just converted to the latest and greatest Sleepyhead testing, 64 bit, open GL, within the last couple of days.

Just thought that it was kind of interesting.

Best Regards,

RE: Leak Rate - Rescan vs. Sleepyhead
Doesn't ResScan attempt to report unintentional leak rate while Sleepyhead reports total leak (unintentional plus mask vent rate) ???

I think that you are thinking of PR machines. I am using an S9 VPAP Auto kind'a like what you have. The machine reports the calculated unintentional leak rate and, to my knowledge, that is what both Rescan and Sleepyhead use.
