What is the mapping between them? Timus has a lot of problems rated < 200, but they also have problems rated above 10,000. The problems also seem more chaotic. I've done some of the first problems, and even the easiest require some tricky thought, but then if I scroll down to more hard problems, some of those are easy.

Does there exist some statistics for comparing timus and cf problems? Or do anyone whos used both sites have an opinion?

If I spend 10 minutes solving A, submit and then spend 20 minutes solving B and submit, I will get less penalty than someone who solves A in 20 minutes, submits, and then spends 10 minutes solving B. This doesn't seem right to me. Seems better to just give people time penalty based on the last AC'd submission (+ possible WA penalties). If someone spends a lot of time solving the first problem, but then quickly finishes all the others, and is done with all the problems 2 hours before the contest is over, seems like that is a stronger competitor than someone who solves all the first problems quickly but really struggles with the last two, and ends up submitting the last AC 3 minutes before contest is over. But with the current system, the latter could potentially fare better.

Is there a reason this isn't the way its done? Not criticizing, just curious if there is a rationale behind structuring the time penalty system this way.

Recently the website looks very ugly for me. There is a big block of empty white space on the right side of the website. I also can't see the blog to the right. How do I stop this? I use brave browser and don't have any plugins.

It almost looks like codeforces is forcing my browser to render to mobile version of the browser.

I have rating 1257. I have done many sorting and searching problems. Should I do other CSES problems like DP and graphs, or is it better to do problems on codeforces. Like random problems or practice in virtual competitions.
