Hey dudes, I'm here in the room too. If you are confused about what I meant you can just ask me for clarification, stop assuming things and stop putting words in my mouth please.
How about this version: Two years is a heck of a long time to spend studying and practicing for ONE standardized test that tests the same narrow set of skills in the same/similar ways every time (no big surprises on the test!). You might get sick of the same old same old after a while. Plus, it is reasonable to believe that with such long term study and practice that you would have hit your peak prepped/studied/learned/practiced score potential in less time provided you prepare/study and practice effectively. There is a concept called the law of diminishing returns.
I can hear it now. A hypothetical conversation between two people that somehow met and became friends while both first started thinking about prepping for the LSAT. Conversation takes place ~2 years after they first met:
A: "Hey B, how's it going?"
B: "Not bad A, and you?"
A: "Good, just finished second semester 2L finals at XYZ Law School, It feels like I got run over by the crim pro final, the fact pattern was cRaZy but I think I did alright on it. I'm going to be clerking for judge PDQ this summer in HappyGetaJobVille and have to move next week. I don't think my cat is going to like the trip, she flipped out last time she was on a plane, good thing the vet gave me those kitty tranc pills. If you are still in the area we should get lunch or something. What are you up to these days?"
B: "I'm working on grouping games, they are kicking my butt. I just did birds in the forest again and got 2 wrong. I made a stupid mistake.
A: "Oh cool, you're teaching LSAT classes and tutoring people now? I hear there is good money doing that, a few of my classmates in LS do that on the side for extra spending cash and drinking $$$, you've certainly been studying for that thing long enough to know it well enough to teach it to anyone. That sounds like a good gig."
B: "ehh, no, I'm not teaching it, canceled my last score and I'm taking it again but am worried because I've worked all ~60 tests at least 3 times each and don't have a new one to use for more timed practice."
