Does anyone know the percentages of people achieving a certain level, I think Level 1 was something like 20%, but how about Level 2?

No percentages, but absolute numbers. See: http://projecteuler.net/index.php?section=scores

But I think the Level 1 and 2 numbers only include the people that have solved a problem within the last 60 days.

That's true. Two weeks ago, we counted and got the following numbers:

Code: Select all

num_solved ≥ 0: 50221 (100%)
num_solved ≥ 5: 29001 (57.75%)
num_solved ≥ 10: 21001 (41.82%)
num_solved ≥ 15: 15122 (30.11%)
num_solved ≥ 20: 11803 (23.5%)
num_solved ≥ 25: 9550 (19.02%)
num_solved ≥ 30: 7715 (15.36%)
num_solved ≥ 35: 6468 (12.88%)
num_solved ≥ 40: 5580 (11.11%)
num_solved ≥ 45: 4854 (9.67%)
num_solved ≥ 50: 4362 (8.69%)
num_solved ≥ 55: 3693 (7.35%)
num_solved ≥ 60: 3195 (6.36%)
num_solved ≥ 65: 2705 (5.39%)
num_solved ≥ 70: 2341 (4.66%)
num_solved ≥ 75: 2058 (4.1%)
num_solved ≥ 80: 1821 (3.63%)
num_solved ≥ 85: 1608 (3.2%)
num_solved ≥ 90: 1411 (2.81%)
num_solved ≥ 95: 1278 (2.54%)
num_solved ≥ 100: 1128 (2.25%)

Since then we got about 2000 new members and the numbers have increased a bit, but the percentages won't have changed much.

I also did this [1] and this [2] a couple of weeks ago
The first one shows problems/people who've solved this many, the second one's the integral

I love the spikes at the round numbers like 100 and 50, or at the 100% mark.
Unfortunately, I don't have numbers for people with less than 25 problems... *shrugs*
