Hey Codeforces!

In the past, Codeforces would hold many of their contests on the weekend. But this month, I've observed that contests are happening less and less on weekends.

In fact, the past 9 contests have all been held on weekdays. The last contest to be held on a weekend was Codeforces Round #692 (Div. 1, основан на Отборочном раунде 3 Технокубка 2021), on December 20, 2020.

In addition, the next two contests (Round #698 and Educational Round #103) are scheduled (once again) not on the weekend. So that makes 11 weekday contests in a row.

Now, weekday contests aren't inherently bad, but many users aren't able to make contests on the weekdays, whether it be due to school, work, or simply being busy during the weekdays.

Is there a reason for the lack of recent weekend contests? Is Codeforces purposely avoiding weekend contests? Do weekend contests conflict too much with other online judges? Is this a ploy to decrease participation so rounds won't become unrated?

Is this all just a notorious coincidence?

In today's contest, problem E is rated 2900. Problem F is rated 2800. But, both in the contest and after, more people had E solved over F. This is good evidence to show problem E is easier than F — but it is still rated lower. Are there other major factors in determining problem rating other than solve count?

On another note, many people gave up after the unrated announcement, and long queues prevented some AC's. Thus, problems D and E especially became pretty overrated. I think ratings of overrated problems due to these issues should be brought down because when practicing, it gives a false sense of the real rating of the problem.
