I have over 200hrs in MSFS and some where around 500 take offs and landings. I have lost count but I would guess somewhere close to 100 different airfields. 90% of those have been remote uncontrolled strips. Probably half are grass. Last time I looked the stats had me at 5 different airports. I have been to 6 ( that one I remember ) starred airports and still show 0 in the stats.
Given the level of accuracy in those stats it doesn’t surprise me when it says I have flown over 500 nm, inverted. Strangely, you would think I would remember that.
