Twenty titles, then pick one

Naming a post, a talk, an email subject line, or a section heading.

Write twenty candidate titles for the piece below, then choose.

Cover a spread: four plain and descriptive, four that lead with the specific number or detail, four that name the problem the reader has, four that make a claim worth arguing with, four short ones of five words or fewer.

Rules:
- No colons splicing two titles together to avoid choosing.
- No "the ultimate guide to", "unlocking", "mastering", "the secret to".
- Every title must be true to what the piece actually delivers.

Then pick your top three, rank them, and say in one line what each one promises and who it filters out. Recommend one. Do not present it as a balanced list.

Piece:

Structure and flow. Order, openings, endings, headlines and the joins that hold a piece together.
