Max pressure different Sleepyhead vs Oscar

Max pressure different Sleepyhead vs Oscar
I finally downloaded OSCAR.  I have been comparing the results and noticed the max pressure on Oscar is reported lower than sleepyhead.  I verified on the chart and Sleepyhead is correct.  Oscar is lower for the 3 days I compared it.  

Here is a screenshot from OSCAR.

I also noticed EPAP is lower.

RE: Max pressure different Sleepyhead vs Oscar
One of the changes that was made in SleepyHead v1.1.0 (and carried over to OSCAR) was to report the 99th percentile pressure instead on the real maximum. The idea was to ignore spikes of short duration; since the change wasn't really documented in the release notes, it has caused some confusion.

A possible solution would be to make a Preference choice between 99th percentile and true maximum, and we would undoubtedly chose the wrong one as default, according to some people.

Thanks for the information.  

Does that apply to all the Max values (Resp Rate, Flow Limit etc....)
