I find too many stats confusing, so the ones I focus on are:
Average words per sentence: 11.5. This is excellent. You can play around and see the difference in voice if you go even lower, but that’s completely optional; and you might like it the way it is.
1 use of passive voice – which is fine.
Flesch-Kincaid Grade Level 5.4. This is excellent, too.
