Yeah, I've heard a good estimate of 200m -> 400m is (200m time * 2 + 3.5s) which would come out to somewhere around 42.5s if he can break 19s in 200m.

Regardless, yeah he needs to do speed endurance, but running +1s in 200m then 2.5 extra seconds to finish the last 200m with work is probably gonna be cake for him.
