Results are pending
This page intentionally has no score or ranking yet. Sync depends on the service, browser, network, device and the exact version of the extension. We will not fill the page with estimated or customer-derived figures just to make a claim sooner.
How we will test
For each service, two people on separate computers will watch the same 90-minute title twice: first after a manual three-second countdown and then in a Watch Peak Party room. At 0, 15, 30, 45, 60, 75 and 90 minutes, both players will be paused briefly and their displayed playback positions recorded.
Every result will state the service, date, browser and extension version, operating systems, network relationship and sample size. Interrupted runs will be marked or repeated rather than silently excluded.
What we will publish
For every completed service test, we will publish all recorded measurement points, median and maximum drift, material interruptions, and the precise test method. The source records will be reviewed before publication.
The page will be added to the site index only after at least one complete manual-and-extension pair has been checked. We will rerun results after meaningful extension releases or streaming-player changes.
What the index will and will not show
The index will describe a defined test setup, not guarantee the same result on every internet connection or streaming title. It will not use customer watch history, party data, chats, voice or video data. Each participant still needs their own legitimate access to the streaming service they choose.
