Each piece asks one question, answers it in the first sentence, and computes every count from the same roster the reviews are built from, with the denominator printed beside it.
2 pieces. Every figure in them is derived from the 39 published reviews at build time, so a correction to a review moves the article that cites it.
A census of the companies we have priced first-hand: how many advertise a figure you can actually pay for a single month, how many cannot, and the three mechanisms that produce the gap.
Price transparency · MembershipsThe break-even month for every prepay plan we can price, computed from each company's own ladder, with the refund terms that decide what happens if you stop first.
Price transparency · Prepay termsTopics are whatever the articles themselves declare. A topic gets a page of its own once 2 pieces carry it — below that the topic page and the article would be the same page. Of the 3 topics these 2 pieces carry, 1 publishes a page.
Carried by these pieces and not yet published as topic pages, with their counts: Memberships (1 of 2); Prepay terms (1 of 2).
Every piece here reads the same roster the reviews read, so a figure in an article and the same figure on a review page cannot disagree. The roster is on the reviews index, the arithmetic is in the real cost calculator, and the rules that produce both are on how we review. Words that recur across the reviews are defined in the glossary.
