The worklist shows the actual work to be done to achieve the goals of the Chemicals wikiproject. The choice of important compounds articles to work on has been finalized in an earlier stage of the wikiproject (around mid 2005), and no further articles are added, although we remain open for strong suggestions on this talkpage. The work these days focuses on improving the articles, from Chem Stub all the way to Chem A-Class articles. The table below shows that progress.
The percentage ≥ Chem Start was indicative of the initial effort. Now that we are progressing to more advanced progress, the weighted progress indicator is used, calculated as (Unclass*0 + Stub*1 + Start*2 + B-Class*3 + A-Class*4) / (Articles*4).

There was also a WikiProject Report in The Signpost in 2012. It is challenging to recognize history when it happens but I think that WikiProject Chemicals might have been a significant and successful attempt at sorting essential information in a way that made it radically more available than anything which had come before. Congratulations to participants here for all that you have accomplished. Blue Rasberry(talk) 14:24, 18 August 2017 (UTC)
