Hello people! This is my take on this retrogression. Looks like the dates may be the dates of the current oath takers as Vorpal had once surmised. Washington DC has moved back to Jan 22 and just yesterday there has been an oath for Maryam82 PD 17th Jan 2007 and the ID was 21st April 2008.
In that respect this theory may hold some water.
This leads me to believe that though there may be some instances where the dates may be more conservative,there have also been reports of 1/2 March 2007 filers ( DC) having got their ILs on the 4th of April 2008 for May IDs. That means people should not lose hope as ILS should keep trickling in. This would be more of an exact 13-15 month timeline as they claim.
Of course if wishes were horses..
Needless to say this situation is exasperating!!
