01Browser tabs and launchers are not the same product
A portal that runs in a tab is judged on load behaviour and panel density; one that ships a launcher is judged on install size, update handling and how much account information the client surfaces before a match. Comparing them on a single 'ease of use' axis produces misleading results, so the catalogue separates the two formats.
02Onboarding is measured to the first real session
We time from landing page to first playable action, counting every email confirmation, region selection and tutorial gate along the way. Portals that front-load account setup before showing any gameplay consistently score lower on access, even when the rest of the experience is well built.
03Scores are revised, not archived
When a portal changes its access model or restructures its menus, the existing score is amended and the revision date printed on the entry. Historical scores are not kept as separate pages, because a rating that no longer describes the current portal is of little use to a reader.
