so from a quick look at submissions, I have the results.
Scoring rules:
earliest buy: 2014 = 1 point, 2013 = 2 points, ..etc to 2003 = 12 points
breakeven: < 0.50 = 10 points, 0.50 to 1.00 = 9 points, 1.00 to 1.50 = 8 points .. etc to > 4.50 = 1 point
Bill couldn't compute his breakeven (couldn't find his abacus). He bought at 1 which after the split is 5, but it's reasonable to assume he pulled this down, so i'm giving him 2.50. I think lebnjb is saying his is 2. So the scores are
lebnjb = 12 + 6 = 18 (gold medal)
bill4810 = 12 + 5 = 17 (silver medal)
alfederici = 7 + 8 = 15 (tied for bronze)
oldguy = 8 + 7 = 15 (tied for bronze)
Alton finished out of the running with 4 + 7 = 11, but he gets an honorable mention for holding Agoracom president rank and for his many diligent computations.
contest is still open for new entries, corrections or re-submissions.
