One thing that puzzles me with the old descriptive notes, what does the K stand for in a K left/right? Someone says the bend should resemble the lines of the letter K but...which ones of them?

At long straights you can often hear description like "braking starts at the bush" or "brake at the road sign" - that doesn't help much in a fog, though. Distances stay the same in any condition.

Sure that works in fog or other difficult conditions. Unless the fog is that thick that you can't see the side of the road, but they will most likely cancel a stage in such conditions.

The only time where the real distance matters is in long straights in fog or dust when there are completely no recognizable points along the track. But there's almost always something that can be used like: "break 100m behind big tree".

Usually neither the pilot or the copilot has the time too look at the tripmaster all the time.

Pretty sure K is used because it's short and easily recognizable from any other note, and not because the corner reminds of K
