And what I'm saying is the whole point of that source is that "A high deviation from the mean will likely result in a lower result next time", but with lower scores (even if they aren't quite below the average - I feel the average is artificially lower due to all the test takers going into it blindly) there's not the same statistical chance of a lower or equivalent score. Of course what romo said is 100% correct as well, but the Dean argument presented is made entirely on statistical grounds, so those are the premises I'm sticking to.
this is not just a feeling, TITCR. if you parsed them out, median would prob be like 159 or something. and that is with Kaplan level training. dedication to LSAT for a solid set of time can let you improve your score.
(I'm not really one to talk through, considering that I got the exact same score twice...)
