Efficiency

This page is a proposal for new Wikimedia indicator

So, it's showing us: how many edits we need to write milions words, how many non-articles we need to write thousands articles and how many stubs we need to write thousands non-stubs.

The efficiency or effective working in Wikipedia (or other websites based on MediaWiki) is a rough indicator of the site's production efficiency, showing how much energy we need to write thousands "good size" articles. A proposed definition of efficiency is:

${\text{Efficiency}}={\frac {\left({\text{Words}}\times {\text{Articles}}\right)}{\left({\text{NonArticles}}\times {\text{Edits}}\right)}}\times {\frac {{\text{Articles}}>2{\mbox{kb}}}{{\text{Articles}}<0.5{\mbox{kb}}}}$

or

${\text{Efficiency}}={\frac {\text{Words}}{\text{Edits}}}\times {\frac {\text{Articles}}{\text{NonArticles}}}\times {\frac {{\text{Articles}}>2{\text{kb}}}{{\text{Articles}}<0.5{\text{kb}}}}$
