Sorry, I mean the total number of people who attempted any problem in that problem set. I think the scoreboard doesn't show you records of people who logged in, looked at the problem, then logged out and went back to sleep, but it will record people who uploaded even a single small input. So if you know that a competition round had 5000 active participants, and 3000 submitted a correct small input, that problem scores 60% for difficulty, and if another round had 20000 active participants, 10000 of which submitted a good input, that scores 50% for difficulty.
You might need to apply some kind of adjustment for rounds though. A Round 3 problem that 22 out of 25 participants solved is still not going to be easy!
