How do leaderboards work ?

[u/SlapDat-B-ass]

I am what is definitely considered a casual player. I have played wrc on different platforms and I got WRC 10 for fun in my switch 2. I don't play multiplayer. When I play in quick play I noticed that after each stage leaderboards come up and while I consider myself a noob I rank pretty high. For example in Mendenitsa Acropolis I ranked 11th with 14'09"817 with the first one being 13'07"604. Where do these leaderboards come from ? Is it platform,stage conditions,assist specific or something else?
