Leaderboards on daily challenge / Distribution of scores


Dear developers,

for quite a time now, I have been observing leaderboards on daily challenges (and my bad or average scorings), today I find the time now to raise this question…

How are results of players distributed?
I really mean this question in the mathematical sense.
Could you please post a distribution example for a daily challenge in Standard and one in Extreme mode, perhaps a quick Excel-made table?

Background of my question is to validate whether it can be true that I am regularly on place 500 (or so) with a passenger count only 20 less than place 10 or 11.


Thanks for spending a thought or even a distribution diagram on this,

best wishes from germany!
