"From 2000, IAAF Rule 260.18s (formerly 260.6.a) was amended to say world records (as opposed to indoor world records) can be set in a facility 'with or without a roof.' So far, only one event - the women's pole vault - has been affected by this change, which was not applied retrospectively. Therefore world records set in 2000 and 2001 by Stacy Dragila and Svetlana Feofanova can be regarded as 'absolute' and appear on these [record progression] lists." [1] (p.546) This rule also applies to Isinbayeva's and Feofanova's 2004 marks.
The IAAF lists Yelena Isinbayeva as having set this mark on 20 February 2004 on their 2009-published progression lists. However, multiple sources elsewhere, including the IAAF's own list of highest women's indoor vaults of the year 2004,[2] state that Svetlana Feofanova in fact set this record.
