Most people only submitted a small handful, other than QM. I haven't looked back in awhile, but as I watched the posts come in, it seemed like very few nations had 3 or more people rate them. You can average 2 numbers, but it's in no way representative of an actual statistical examination.
Granted, it'll be hard to get enough to really give anything excessively accurate - but it shouldn't be hard to get a lot more ratings than we've got so far.
