Ooops, the tournament was in 1988
14.4 might means 14 years and a 40% of an year (4,8 months, or 4 months and 24 days)
He was born in 12/31/1973. It's really not like the 2nd link I posted says(14 y3m) , and the first just says 14 years old (but mentions the correct year, 1988, not like the first).
Voo, I have to say I love the stats you bring (I know I already did it, but now it becomes public). Thanks!
