Every product page on Virtual Meeting World carries an Expert Score out of 10 and a star rating. This page explains where those numbers come from, which criteria count in each category, and how much each one weighs. The same rules apply to every product in a category, and they are applied by the same scoring engine every time a product’s data changes.
What the Expert Score is built from
The Expert Score is calculated from official specifications and features: the manufacturer’s spec sheet, product page, support documentation and certification listings. It is not a hands-on test result, a reader poll or a sales ranking. If a manufacturer publishes a figure, it can be scored. If it does not, we leave it blank rather than estimate it.
We only mark a feature as absent (“No”) when an official source confirms it is missing. A spec we could not find is shown as a dash and is skipped, never scored as zero. You can read more about how we source and check data in our Editorial Guidelines.
How the score is calculated
- Spec scores. Each spec that feeds a criterion is converted to a 0–10 score using a fixed rule for its category. Some rules are scales (for example, more lumens or a longer talk time scores higher). Others are lookups (for example, 4K scores higher than 1080p, and a built-in privacy shutter scores higher than none).
- Criterion scores. Each criterion is the weighted average of the spec scores available for that product, from 0 to 10. Missing specs drop out of the average instead of dragging it down.
- Expert Score. The criterion scores are combined using the category weights listed below, then rounded to one decimal place.
- Stars. The star rating is the Expert Score divided by 2, shown to one decimal. A 9.4 Expert Score is 4.7 stars, not a rounded 4.5.
- Criteria that don’t apply. Some criteria only make sense for some products. A wired headset has no battery, and a monitor arm has no companion app. In those cases the criterion is marked as not scored and its weight is shared among the remaining criteria, so the product is neither rewarded nor penalised for something it was never meant to have.
Our scoring rules allow an editor to adjust a single criterion by up to 2 points when there is a documented reason, such as a confirmed firmware change the spec sheet does not yet reflect. No adjustments are applied at the moment. If one is ever used, the review will show the adjustment and the reason under its score table.
Criteria and weights by category
Each table lists the criteria for a category, the share of the Expert Score each criterion carries, and the specs it is built from. The percentage after each spec is its share within that criterion.

How comparisons use the same data
Our comparison pages draw on exactly the same specifications and scores as the product pages. Criterion scores are shown side by side for each product, and the higher score is marked as “Better”. In the full specifications table, the stronger value is highlighted only where higher or lower is clearly better, such as a wider field of view or a lighter weight. When a spec or score changes on a product page, every comparison that includes that product updates with it.
When scores change
Scores move when the underlying data changes: a manufacturer publishes a new spec, corrects an old one, or releases a firmware update that adds a feature. They can also move when we refine a category’s rules, in which case every product in that category is recalculated together so the scores stay comparable. The updated date on a product page reflects the last meaningful change to its content or data.
Prices and affiliate links
Prices are shown when a current retailer price is available; otherwise you will see “See price”. Some links on the site are affiliate links, including links to Amazon, and we may earn a commission if you buy through them. Affiliate relationships have no effect on the Expert Score: the score is calculated from specifications before any price or retailer is considered. See our Disclaimer for details.
Questions or corrections
If you spot a spec that looks wrong or out of date, email [email protected] with the product name and, if you can, a link to the manufacturer’s page. We check every report against the official source and update the page, and the score with it, when the correction is confirmed.
