Thanks for the post. And thanks for your perm breakdown which saves hours of work and effort that I was expecting to spend

.
From the perm breakdown data that you posted:
Jan 2007 to Dec 2007 (perm approved after Aug 17): 15,360
Jan 2008 to Dec 2008: 27,715
Jan 2009 to June 2009: 10,416
Jan 2009 to Dec 2009: 18,789
Total from Jan 2007 to Dec 2008: 43,075
Total from Jan 2007 to June 2009: 53,491
Total from Jan2007 to Dec 2009: 61,864
With a OR of 0.8 as the perm to 485:
Till Dec 2008: 0.8 * 43075 = 34,460
Till June 2009: 0.8 * 53491 = 42,792
Till Dec 2009: 0.8 * 61864 = 49491
So with these numbers, shouldn't 40k reach somewhere in April 2009 and 50k will be around Dec 2009? You had mentioned 40k is till nov 2008 and 50k till 15-jun-09. Am I missing something?
