Perch uses the rounded estimate of about 50¢ per mid-sized PR, approximately 150 methods read at the captured September–October 2026 density of 34 questions per method. At 10¢ per 1,000 fresh checks the unrounded example is 51¢ per PR. Scope, cache hits and repeated reviews change usage. A vendor subscription floor excludes any additional charges and does not guarantee that every review is included. Credit packs, diff kilobytes and reviewed files cannot be converted into PR totals without their usage assumptions. Perch estimate inputs.
