Hi, I recently updated my MBP to the El Capitan beta and the addition of GeoTagging encouraged me, after a full backup, to jump from iPhoto to Photos and pay the $3.99 for the 200GB. My MBP says that my old iPhoto library, now referenced by Photos, is 113GB in size. After three days, my 20000+ photos are now uploaded into iCloud. I've closed and reopened Photos a few times and it tells me that the uploads are complete. However, when I go into Manage Storage, iCloud is only reporting that my Photo Library is 74.9GB. Could I have lost some photos/videos during the upload? Or is something else going on here?
