How? Well in GOM Classic Season 2 the information for the Round of 64 Part 1 was incomplete, with only the information of the broadcasted matches being available at the time. I just found the results for the unbroadcasted matches, and upon adding them to TLPD, the trickle-down effect was enough to push EffOrt to the 2300 mark on the dot. You'll notice that current ELOs have jumped by a bit, and some ELO peaks are a bit higher now (I believe Jaedong and Bisu's have both been boosted a couple points). So congratulations to Kim Jung Woo!
