Let's use our MCAT math skills, and remember what a significant figure is, and how rounding works.
The percentiles are all given rounded to the nearest tenth of a percent. From 2009, 0.1% of examinees are said to score a 42, those being contained within the 99.9 - 99.9 percentile. 0.0% of examinees are said to score each of a 43, 44, and 45, also contained within the 99.9 - 99.9 percentile. This doesn't mean that no one scores above a 42. It means that the total number of people scoring above a 42 rounds to 0.0%, not to 0.1%. This suggests that less than 0.05%, or less than 40 people do this well. My feeling is that the number is substantially less than 40 people, but not 0 people.
For scaled scores in the 40s, it's frequently the case that each wrong answer corresponds to a point lost on the scaled score. Let's assume this is the case, and see where it gets us. For examinees scoring in this range, there is a large number of questions, and a very low chance of them missing any given question. We could thus model wrong answers with a Poisson distribution. If there are 80 people with an expected score of 42, and thus an expected number of wrong answers of 3, we can look at the Poisson distribution and see that about 1 in 20, or 4 examinees will, just by luck, get every single question right, and thus a 45. Another 12 or so will, just by luck, miss only a single question, and get a 44. And about 18 will get, by luck, a 43. As a sanity check, consider that we've calculated a total of 34 scores above a 42. This is entirely consistent with the published data, which implies that fewer than 40 examinees score above a 42.
It would actually be really strange and unexpected if no one ever got a 44 or 45. We know that close to a hundred people are getting a 42 each year. How likely is it that none of those bastards gets lucky and misses zero, one, or two questions, instead of three? Pretty unlikely.
All that said, is every reported score on here accurate? Probably not. Some guy on the internet says that his friend's brother got a 44. Is it true? Who knows. Some guy on the internet says that Obama was born in Kenya. Some guy on the internet says that tinfoil hats keep out the satellite waves. Some guy on the internet thinks that everyone cares about the cute thing his cat did the other day. Actually, he's probably right about that one, strangely enough.
