Forum:World Standard Championship?

Does anyone have any idea what the World Standard Championships are/were? "WS1" and "WS2", for "World Standard Championship 1" and "World Standard Championship 2", respectively, have been listed on the image policy as in-house abbreviations (implying that these championships would have taken place before April 20, 2000) since August 7, 2006, when TwoTailedFox added the entire in-house set abbreviations section to the policy page. The only other relevant mentions I can find of these sets/championships - either by name or by abbreviation, and either using the built-in MediaWiki search on only this wiki or Google search across the entire internet - are on User talk:Taylor, where the abbreviations were first listed by Narchibald84 at 12:37, July 30, 2006 (UTC), and on User talk:BadPlayer, where TwoTailedFox posted an almost identical message at 17:09, July 30, 2006 (UTC). It is possible that there are earlier mentions in page histories, but there is no simple way of searching those short of examining a database dump, and even that wouldn't catch potential mentions in deleted page histories. Does anyone know anything about this? 「 ダイノ ガイ 千？！ 」? · ☎ Dinoguy1000 07:48, February 14, 2011 (UTC)
