Well if people share their scores, what do you hope to find? If someone with higher scores post, you get more depressed. If someone with lower scores post, you feel happier about yourself but the new guy is now pissed off seeing your score and existing listings (presumably higher.) it also can backfire on admissions when someone go to them and say "hey, why you guys interviewed someone with lower test stats than mine instead of me?"Agree. When I tried to dig some information from last year's tracker, it's frustrating to see that not many people shared their profiles (aka test scores, gpa etc)...Based on limited samples, I sensed a taste for higher standard test scores from Columbia...I mean, even verbal seemed to play its part...not a good news for me
So don't get too stressed about the scores. Comparing them should be treated as nothing more than pasttime. People who actively post are usually 1) showing off, or 2) hoping for a miracle. The fact Is that competition for all graduation schools are tough, and students a running out of ways to distinguish themselves (that's why verbal scores start going up as well.) Normal distribution of the applicant pool dictates that for every class, there will be a few perfect scores+4.0+blue chip WE and then some dogtown school+poor gre+no WE with the MAJORITY of us lying somewhere in the middle. So most questions asked here are by individuals with one or two "shortcomings" who hope that his isn't as detrimental as his neighbor's, yet only a few people in the world can decide that and the rest are just noise and opinions for a feel-good moment.
All you can do is simply doing the best you can on your applications, going away for two month, and letting admissions do whatever they wanna do. It's really really not worth stressing out about given the element of randomness and lack of control you have toward the admissions process anyways.
