I don't know if it's obvious. For example, everyone always assumed ski jumpers should keep their skis together in the air, then someone realized the V technique with the skis spread wide actually allowed jumpers to travel farther.
How does this apply to swimming? I think conventional wisdom would suggest keeping the fingers together would be better because water wouldn't be able to slip through. However, spreading the fingers somewhat might actually increase the effective surface area--just like wearing paddles does.
