I agree with no more than one thought per sentence in general, though I have the opposite problem: it often takes me several paragraphs to get a single thought across. So the end result ends up being something like 0.1 thoughts per sentence.

I guess what I'm trying to get across is not a single thought but a perspective which requires some background and context to appreciate, and I struggle with separating out the essential from the incidental, and structuring it for maximum engagement.
