The Wikipedia essays in this category are very important to Wikipedia:WikiProject Essays, as they influence opinion and/or are widely read and discussed by Wikipedians. Essays with a weighted scored rank from 11-50 are considered high importance, putting them in the top 5% of Wikipedia essays.
The weighted score system takes into account number of page watchers (W), pageviews in the previous month (P), and number of incoming links (L). As all three of these metrics are subject to change, essays may be re-rated month-over-month. The importance of essays is determined based on their rank in the list of essays sorted by score. The score is calculated with the following equation: W*10+P*2+L/100.
