Danny McCray raised an interesting point in an off-list post, and that's that the "WR" that Marion Jones is going for at Mt. SAC, 34.1, was run around two turns (because it's the 300 split in Marita Koch's 47.60 WR in the 400). Marion will have the advantage of only having to run a single turn. So unless she runs about 33.5 (plug in your own number here if you like), I'll still consider Koch's mark the superior. gh
