Fungi of Yi Ti

In The World of Ice & Fire, it states that "when men at last returned to the isles to live, they were men from Valyria itself. Thirteen hundred and twenty-two years before the Doom, a sect of religious dissidents left the Freehold to establish a temple upon Lorath’s main isle." The doom of Valyria was 102BC, which means 102+1322 = 1424BC? But the wiki (both the Lorath page and Timeline page) says 1436BC. What am I missing here?
