Coincidentally, I had a parent/teacher conference with my 1st grader's teacher yesterday afternoon. Regarding reading level & comprehension, she remarked that current research indicates anything below about 98% comprehension isn't sufficient for reading "fluency". Before the past few years, the standard was 95% comprehension = fluency, but that extra few percentage points apparently make an enormous difference (probably because of colloquial & jargon edge case usages that carry specific meanings in specific contexts, but which aren't easy to programmatically detect, but that's just my supposition).

Sorry, but that just doesn't make any sense to me. Practically 70% seems like enough to understand most narrative. I've read some really difficult texts (translated German theology) and for anything of meaningful complexity 98% is unreachable without a huge vocabulary and understanding of both oddities of grammar and the construction of narrative or argument.
