it's not all easily compared like you are making it.
There you go...you made my point. It is NOT easily compared.
Last time the office we went through was audited was in 2005 as well.
Our application was done in 5 months from the date it arrived in Mississauga. You can't know our situation of course, and you don't know what our paperwork looked like either, so you can't compare our timeline to yours. But, in the end my wife received her visa without an interview or any further requests for information and in the meantime she had managed to get a temp visa as well to visit over Christmas.
Your situation is possibly more complicated, harder to verify, going through a busier office, relys on paperwork proof that is less reliable, or perhaps some combination of all of the above.
