swimnews.com has an interesting article about Amaury Leveaux's 21.38 50 free European record:

Leveaux's drop from 22.80 to 21.38 makes him somewhat of an anomaly among the 200m competitors in that 200m contenders (ranked 3rd in 2008) aren't normally competitive in the 50m event (ranked 2nd all time). Perhaps he's been training for the wrong event?
