In May 2009 WP:LAYOUT conducted two studies.[A] The first was to determine the proportion of section titles used in the standard appendices of all articles within the English Wikipedia.[B] The second was to determine the degree of conformity in all articles within the English Wikipedia as defined by WP:LAYOUT.[C] Below are the results.[D]

At this point the author would like to interrupt this list to indicate a possible application of the value attribute found in Template:Cnote2. Very long lists similar to this one may benefited by having it be broken down. Remember to remove the link to an inline occurrence, giving the feel of an regular list, set n=0.
