First I want to say that I apologize to everyone who has been using Internet Explorer - I just installed Windows on my computer and thought I'd see how well it worked... and, well, lots of stuff didn't. But it should work now, so if you experience any issues please let me know. (Also, I'd advise switching your browser to something more modern
To Yukos and Wormfather, I think you both raise good points. I think there are lots of problems in general with the data on LSN, and this is one of them, but while half or even more of the people who would be YP'ed at a certain school will withdraw and, thus, not have the would-be waitlist recorded, there are still a few people who will (as we have seen) and, thus, there should still be a record of the YP occuring. But what you say is particularly interesting because the YP could be significantly worse than one would expect based upon LSN.
In general, I think the graphs are a much better way to examine one's chances at a school than the search feature, because with the graphs you can see if the point you're searching is just some sort of statistical anomaly, and you can see how much of a buffer you have. By that, I mean that if you are a green point, and you have a bunch of green below (and to the left) of you, then you're safe. On the other hand, if you're a green point, but you're just above a sea of red, your chances might be heavily dependent upon the cycle you're applying in and maybe even your softs (crazy, right?
In any case, that's a bit besides the point. You have a great point, and I think it really serves to show one of the many ways in which the meaning of the information on LSN, and thus MyLSN, is obscured. It's important to bring things like this up, though, because it does create the possibility of someone coming up with some sort of way to avoid the problem (though, unfortunately, like you suggested, I, at the very least, can't think of a way to solve this one).
I think this is my longest post on TLS...
Hope you all are having a great weekend!
