First, your "question" is unintelligible as written.

What I mean to say is... Do you think there are some people who can never really achieve a certain score even with an unlimited amount of study time because of factors such as lapses in focus, inability to process/handle multiple pieces of information at one time, inability to make correct inferences, etc etc etc.
What do you think?
Re-read the wording used in the sentence/question beginning with "Do you think..."
In addition to the fact that the wording doesn't make sense - even though I can discern what you are trying to say - you failed to properly punctuate your question, and there's the rub. To raise the proverbial "ceiling" you speak of, mastery of the English language is paramount. Many test-takers experience the ceiling because they have failed to acquire the requisite reading, writing and speaking skills necessary to effectively navigate the test.
I mention writing and speaking because the two are almost inextricably bound to the act of reading, i.e. people tend to perform all three with similar levels of proficiency. Hence, the answer to your question is "Yes"!
Everyone has a ceiling, but those ceilings are determined by various factors unique to each individual. Moreover, there simply isn't enough time in most cases to undo the bad language habits that most test takers have acquired over several years.
I really don't mean to be a gunner here (I wish everyone well, including you), but you have illustrated perfectly in your writing why, despite the LSAT being very learnable, many test takers will never be high scorers. Superior command of the English language is the key to the entire test, and most people have neither the time nor the inclination to undo their deeply ingrained habits.
