Okay, I tried searching, but couldn't find anything. It's a pretty basic question. I found diagramming at first fairly challenging, yet have gotten much better. I find it helpful when doing the blind review to confirm my answer. However, on actual timed PTs, I find there just isn't enough time. Often the arguments have far too many wordy concepts that are difficult to diagram, and I end up just confused between terms. I find, more often than not, diagramming eats up a lot of my time, and I am getting better and better at just seeing the answer by reading the questions. Although I still diagram the questions that have many conditional statements and are very simple sentences, anything that is very complex, I find diagramming under the time pressure doesn't help me. Is it fair to say that diagramming LR questions (e.g. parallel, PF, and especially SA questions) is mostly for just learning the conditional statements, and strengthening the learning so that it becomes somewhat intrinsic? It seems to be working for me so far since I have had significant improvements, but just wanted a second opinion on this.

It's definitely fair to say you don't have to diagram if you can see the answer just by reading it. I know a lot of high scorers who have practiced diagramming and argument forms so much that they can just see what's missing without even having to draw it. This gives them speed as well.
However, if you do miss a question that requires diagramming I would work on understanding in Blind Review what about the question gave you difficulty. Was it logic? Was it not being able to shorten ideas so they are easily diagrammable? or was it grammar?
So I think the answer to your question is definitely depends. Like you said, you are getting them correct, in this way its fine to not diagram them. But if you get them wrong, definitely take your time to learn it and see how in future you would act if you encounter a similar question.
