just a side note that surprised me, the lock on SD cards only works if the software driver handles it. It is not a physical disconnect, it's only a status to be checked.
I too have the p10 nasal pillow mask and looking at your leak graph I noticed your leak rate never gets down to zero. My first mask, the leak rate started at 2 awake or sleeping. Once I got my first replacement, my leak rate stayed at zero until I had a true unintentional leak. This may not be anything, but my 90% pressure has come down, and sleep quality has improved.
Leak rate was decent, no events on CPAP. What do you think caused you not to sleep well?
