@SaiksyApo: you can't compare with a race. A contest is a race (especially the solo ones) but the global leaderboard is more like a championship. But in sports, and even now in some games, it works with seasons: so if you arrive in the competition during season 3, you probably won't be able to rank well for this season but from the next one nothing is preventing you to reach the top. Lots of games are using either ELO or TrueSkill or variations of it, which both avoid having unreachable players. Or, to have an example of a continuous ranking, have a look at how ATP is working. If it were like Codingame, Federer would still be 1st by a very large difference.
By the way, what if this logic were applied to a single multiplayer contest on CodinGame? Won't you be bothered that the ones who push first could earn more points to such an extent that maybe people with a way better AI won't be able to catch up?
@Neumann: Yes, you're 14th, but you are 5600 points away from the first, this is almost the double of what you have now. And as the 3rd of this leaderboard, I don't see how I could be pushed away from the top 10 before years thanks to the 2700 points gap... Even the 4th has 800 points less than me so I'm kind of locked at this place as long as I do every contest, which is a bit sad for both me and anyone who deserves this place more than me.
