Whats everyones view on oil level?
Bought a GS1200adv from a BMW dealer last year with oil right at top of sight glass, 3k later 80% of glass covered and service due.
Decided to go to local independent for 6k service (BVM Stroud) and was advised always aim to run with oil in middle of sight glass when bike is stone cold.
Whats everyone else's approach to both "the level check" (do you do the BMW 5 minute check or a cold check).
Do you also keep it banging on the top of the sight glass or middling?
All thoughts, piss takes and observations welcome?

Why do others think they know better than a company who spends a whole heap of money on R&D and testing?
