It is mentioned everywhere that shhs1 consists of 5804 records, but there are only 5793 edf records on the server. Why? Is it possible to download remaining 11 records?

The 'shhs1' dataset does contain 5,804 records (corresponding to 5,804 overnight sleep studies), but only 5,793 usable EDFs were retrieved from the SHHS archives for posting on sleepdata.org. Unfortunately, those other 11 EDF records were lost over time, most likely due to data corruption at some point long ago.
