RE: Statistics not the same as Overview
It looks like there wasn't any detailed data for those 6 days in May on your current SD card.

April 30 looks like you didn't use the machine at all.

Have you changed SD cards recently?

Yes, new card was installed a couple weeks ago. Doesn't the DS GO store 6 months of data?

RE: Statistics not the same as Overview
Sort of. It will store 6 months of summary-only data, which is just settings and times of usage (and evidently some summary AHI that OSCAR doesn't yet know how to read).

It also stores about 7 days of detailed data, which includes all the respiratory events and stats during the course of the night, from which OSCAR calculates AHI. It does not store (and therefore will only record if the SD card is inserted) high-resolution waveform data such as flow and mask pressure (for ventilators).

If you now import from the older card, OSCAR will most likely see the summary-only sessions from the new card and skip the details that were present on the old card. I think that if you force a rebuild of the data (Data > Rebuild CPAP Data > your device), it might import all the details from both cards, since the backups should include all of the data.

If that doesn't work, then you can create a new profile, then import the older card first, and THEN import the new card. That should give you complete data. (If you have other data in your current profile, such as oximetry or journal notes, you could alternatively try purging the machine entirely (Data > Advanced > Purge ALL Machine Data > your device) and then importing the older and newer card, but I'd make a backup of your OSCAR_Data first just to be safe.)
