My MSFS logbook has not kept a running record totally. On occasion, it rolls my hours back. Now MSFS states I have 725 hours, where six weeks ago I saw over 800 hrs. Who knows. Steam reports I've spent 5529 hrs in MSFS in the past four years. Yes, fifty five hundred. I divide my time between MSFS and ATS (1610 hrs). Hopefully MS2024 will have a more accurate record keeping module. Steam reports over 2800 hrs for FSX. This was after I transitioned to Steam edition. I've been using Flight Sim since 1983, Bruce Artwick's jewel.
