The Impact module displays the number of views for an article edited by the user. But if they edited the article yesterday, they have the sum of views from the last 60 days.
A user reports on Danish Wikipedia that it embellishes the actual number of views. This user suggests to change the current sentence on MediaWiki:Growthexperiments-homepage-impact-subheader-subtext to something like:
Number of views in the last 60 days, of the pages you edited.
