If I remember correctly, the NYTimes is written for the 8th-grade level. Similarly, many hospitals/healthcare facilities don't allow writing above the 8th-grade level. So, expressive, detailed, and stylized writing are all easily possible at the 8th-grade level. In fact, I probably write at the 8th-grade level, albeit less clearly.
What's the gap between an 8th grade reader and a 6th grade reader?
