A wiki page is complete if and only if the requirements for incomplete are met and furthermore the following conditions are fulfilled:
- all applicable sections are filled in
- the example section contains a thorough discussion (most likely containing code and/or diagrams)
It is still possible to enhance a complete wiki page even further by detailing the discussions or adding further examples, etc. But there should be no real gaps anymore.
In order to see which wiki pages are complete, use the backlinks feature of the wiki software.
