The number does the work, 164 books in one year is a count you have to double-check. The wall of covers makes the scale visible rather than claimed. The should-and-shouldn't line then turns all that effort into verdicts you can actually use.
How the packaging works
Title
The title states the exact count and promises a one-sentence verdict on each.
Thumbnail
The thumbnail buries the creator in a wall of covers and promises reads to skip as well as keep.
Remix this
Use this when the sheer volume of your work is unusual. State the exact count and show the pile, because a visible wall beats a claimed number. Keep the count honest, commenters will audit it.
The transferable lesson
An exact count plus visible volume beats any claim.
