Depends on what's worthwhile for people I guess, from a racing standpoint where rule restrictions are in place I'll typically take it where I can get it and with it being a none to costly or timely modification it just makes sense to make the efficiency where ever you can.

I would guess it is due to fewer total degrees of tubing angle and thus turbulence in flow that makes the difference, not so much tubing length.
