Lubeck To Kiel: How To Get 1000 Points (gold)?

In Wintery Lake scenario I made no errors but my score is 800 points -- silver. Is it a bug or is there a way to get 1000 points (gold)? The same is for Summer Slip.

 

I haven't tried this scenario, sounds like it's what I call "the maths" issue...there's a number of scenarios where not enough points were allocated to each stop/target making 1000 impossible.....

 

Thanks, but in the rating I can see some players with 1000 points for such scenarios.
