I think 2200+
It's your second account, am I right? You wrote 1 contest with 2 accounts. Maybe you're cheaters?
Actually about 2800~3000, but IOI offers a larger duration for problem solving, so they're not that undoable.
Most people say something like 2000+ but at 2020 IOI i got a full score for super trees while i definitely can't solve a 2000+ rated Codeforces problem. (I was specialist at the time with 1696 max rating. LaKsHiTh_)
super trees is definitely atleast 2100 rating(probably more)(if put in a 2hr cf contest)
I think i spent more than 2 hours for that. But i still don't think i can solve a 2100 even if i was given a day.
one problem and one person is a very small data point
