Ok, since I'm bored, I did some maths.

By my calculations, as the levels on your advantages advance, the ratio of people with that level of talent to the number of people without that level increase in alternating degrees of 100 and 10 (in terms of sword at least); like so:

Level 0 = 1 in 1 (kind of)
Level 1 = 1 in 100 (*100)
Level 2 = 1 in 1,000 (*10)
Level 3 = 1 in 100,000 (*100)
Level 4 = 1 in 1,000,000 (*10)
Level 5 = 1 in 100,000,000 (*100)

So following this pattern, I figured that the later levels would look like this:

Level 6 = 1 in 1,000,000,000 (*10)
Level 7 = 1 in 100,000,000,000 (*100)
Level 8 = 1 in 1,000,000,000,000 (*10)
Level 9 = 1 in 100,000,000,000,000 (*100)
Level 10 = 1 in 1,000,000,000,000,000 (*10)

Apparently, the total amount of homo sapiens (humans) who have ever lived on the planet earth is around 108 billion (according to the Population Reference Bureau, apparently), meaning a level 7 swordsman almost has more talent than anyone who ever lived in modern time, and a level 10 swordsman has a talent in swords of 1 in over 9000 times the amount of people that have ever lived in the modern world, meaning that kind of talent will practically never be seen again.

gg everyone, correct me if I'm wrong.
