There are two ways of accepting countries that overlap continental lines. Either you take the European part and count that for Europe (and do the same for the Asian part) and if that's enough you add it to the corresponding list or you take the population as a whole and apply that number to both lists. For Russia, you used the second method, otherwise it would have never made the Asian list, but for Turkey you used the first method, because if you used the second, it would've appeared high on the European list.
I just think you should stick to one of these lists, which one, I dont really care. In short, you should either add Turkey to Europe or remove Russia from Asia.
