    Because the measurement system references back to a point behind the line; it is a choice, but the more natural one, I think (and might be in keeping with rules across events).

    Good question. Why couldn't the foul line be a straight line instead of an arc?

    It also means that at any distance n meters from the center of the circle (n-8 meters from the arc) the sector lines are n/2 meters apart, which in theory provides a quick way to check if the sector has been measured and marked correctly.
    So what is the origin of the 8 meter radius?

    Hey, in any case I've got a great story problem in the bank for next year's classes.

    What I don't understand is why the sector wasn't checked before the meet. Did the Official Surveyor not do his job properly? Under Rule 135, he/she is supposed to check the accuracy of such things before the meet. What about the Technical Manager, who is responsible under Rule 123(a) for ensuring that all of the sectors are in accordance with the rules?

    Obviously all throwing events need a sector from a safety point of view, and for standardisation of circumstances for comparison and record purposes.

    People have been impaled by javelins going outside the sector. Without the sector restriction, the throwers would be less careful about the direction of the spear, resulting in more such injuries and deaths.

    The replay clearly showed that the officials did extend the sector line (as drawn) and it was still out. Remeasuring the sector opens up all sorts of mischief to be played. When the point is 100 yards removed from where the angle is measured, a fraction of a degree can be greatly magnified to many inches. My guess is that they gamed the sector that way and you know what I think about that kind of shenanigans? I LOVE it!

    If this is the same Yego who got away with an obvious line foul in winning last week.(.or was it two weeks ago?.) the javelin gods are smiling on him.

    Quick question: how accurately are these sectors measured and marked in the first place? The difference between a sector angle of 28.96° (what it should be) and a sector angle of 28.86° is about 15 cm that far out, and the sector line didn't appear 100% straight.

    Supposing that actually is what happened, was it the right decision? Should the "real" sector angle of 28.96° trump the dreaded white line?

    Ditto. I had the same impression, but I have the same reservations about calling it out. From the camera shots we saw on tv, it was hard to be absolutely sure. I think we have to trust the officials on that one.
