Oscar: overview graphs question/oddity
Due to my own stupidity, I ran my cpap from Jun3 thru Jun 12 without the SD card installed.
Imagine my surprise today, when importing data from SD (today being Jun 14) and I find certain graphs on the Overview page (AHI, Usage, Session Times) show data for the period when the card wasn't in the device! Go figure!
Can anyone explain to me where this data came from?

RE: Oscar: overview graphs question/oddity
No surprise, that's all summary data, no if you can bring up daily charts for those dates, well, that would truly be a surprise.
RE: Oscar: overview graphs question/oddity
You're right, there is no daily data.
but still, the SD card was not in the machine during those days/nights, so where did that data come from?
RE: Oscar: overview graphs question/oddity
It is stored internally, then written when the SD card is re-inserted.
