Sometimes I go hours without docking. It's a good idea though, but then again I haven't been playing for as long as some of the more senior members here.
Personally I never forget to save as i've had several game crashes happen. One that even deleted my save game although thanks to quick save doing a backup of your last saved game before, i didn't end up losing more than 5 mins of gameplay (without the backup i'd have lost more like 4 hours since i'd been constantly saving on the same savegame, something i don't do anymore either, i always save on a different file every time i save) I don't think i ever go more than 5 mins without saving (except if i'm on a mission that lasts longer than this). As a PC gamer i have decades ago learned the value of constant saving:-p. In fact, i dislike autosaves because i hate the game dictacting when i want to save.
