What this does not establishA smoke test that the journey is unbroken and attribution survives the hop. n = 1 per device: it is not a benchmark of anything.
RevalidationRevalidation required. The builder has changed since this was measured (tested against 7087e916cc72, now 81b06938d243); The site generator has changed since this was measured (tested against 7ced1fed10e7, now 4f6c43a055d4).

Citing this
https://veloci.build/evidence/ad-to-stripe is the address for this figure. It carries the method and the limitation; a marketing page carries neither. If the number changes, this page changes with it.
Fingerprints are sha-256 (first 12) of veloci-builder.html and of compare-src/build.mjs at the time of the run.
Partner programme
Every business finds Veloċi somewhere: an ad, a search, a friend. We'd rather pay the friend. The fees are our advertising budget, paid to the person who brought the customer instead of to Meta, Google or Bing: $19 to $94 a package, plus hosting and mailbox fees every year they stay. The customer pays the same price either way, every partner must say so wherever their link appears, and we never pay for a review.
