Definition
This measure counts WordPress plugins first listed on WordPress.org after a stated date that have entered the top 12,500 plugins. It counts how many newer listings go on to reach a measurable popularity rank inside the ranked part of the directory. It does not track listings that stay outside it. The stated start date is fixed and carried forward across issues.
Population and window
Rivale measures this for plugins first listed after a stated date. It counts those holding a rank inside the top 12,500 plugins as of the issue date. The window is the report month, counting plugins that entered the top 12,500 plugins during that month. The count grows across issues as more plugins from the same starting group cross into rank.
How it is computed
A count of plugins whose first listing falls after the stated date and which hold a rank inside the top 12,500 at the date of the issue.
How to read it
A plugin counts here only once it holds a rank inside the top 12,500 plugins at the issue date. The stated start date and the issue date together set the scope of what this figure counts. Read it beside new plugin outcomes to connect this figure back to the month a plugin was first listed. Read it beside departures from the top 12,500 plugins to see arrivals and departures from the ranked set together. A plugin that enters and later leaves the top 12,500 plugins still counts here as an entry.
What it is not
This measure does not count every new listing on WordPress.org from the stated date. It counts only the ones that reach the top 12,500 plugins. It does not state a plugin's exact rank or install count once it enters. It is not a measure of plugins leaving the ranked set, which departures from the top 12,500 plugins covers separately. It is also not a measure of how long a plugin took to reach the top 12,500 plugins. It only says the plugin had done so by the issue date. It is not reset each month. It counts against the same fixed starting date across issues.
