I don't know if its pessimistic, its just reality. Law school applications are expensive. I don't know what extra value there is in sending an application before you know where you stand. I could have saved myself a few hundred dollars. I was speaking from personal experience.
Plus, what if they are higher? Then you lose nothing because the higher than expected LSAT score should compensate for your application being reviewed a few weeks later. This is of course assuming getting your application reviewed 2-3 weeks later in January is a disadvantage which I am not sure I would concede.
I asked admin officers if I should do it, and most said it didn't matter. One (UChicago) said I ought to send it in early. After I got my score, I had no business applying there.
All my experience. Do with it what you will.
