The doubt arises from the fact that no person in top 10 rated list currently has won(rank 1) all contests he/she participated in. And the current max rating is of tourist (3739) and not even tourist has won all contests.

So , I was wondering what if someone existed who had participated in every possible rated-contest on CF and got rank 1 in all of them. What would his/her rating be?

I know that's a totally hypothetical situation but it's kind of interesting and so I am curious. Will there ever be a point where even rank 1 will give +0 delta? And what would that rating be?

Is there any way we can calculate this? Is there any web-app or script that can tell us this?

I manually calculated it for all Global Rounds using virtual contest rating calculator and the rating changes turned out to be:

(default)1400->2045->2451->2761->2959->3137->3257->3373->3461->3539->3579->3635

In CodeForces, rating is calculated by comparing your seed (the place you're expected to achieve, calculated by a formula using your rating and rating of those who participated) to your actual place. Your seed is always greater than 0, although it could be infinitely small. Thus, you will always get positive delta if you place first, but rounding may turn it into 0.Is there any way we can calculate this? Is there any web-app or script that can tell us this? If you want to calculate this, you'll have to calculate ratings for each contest. The best you can do is write a script that does so with cfviz. I would guess that the rating of this person would easily exceed 4000 though.
