Talk:Women's 50 kilometres walk world record progression

Previous WRs
Here (https://www.iaaf.org/disciplines/race-walks/50-kilometres-race-walk) IAAF has listed under best times of 2017 season 1.) 4:08:26 (which is official world record time) and 2.) 4:22:22 by Yin but under all time list there are 2.) 4:10:59 by Monica SVENSSON in 2007, 3.) 4:12:16 by Elena GINKO in 2004, 4.) 4:16:27 by Jolanta DUKURE in 2006. That means that there were either previous WRs or unofficial WRs/unratified WRs. What is the deal with those results? Those results should be included in the table in some way.  213.149.61.126 (talk) 14:59, 20 July 2018
