I've done some detailed analysis for Manila VO compared to last year around this time......the reason I chose relatively equal time of year is because Manila VO is fairly consistent reported processing times on CIC website, but their actual times fluctuate within the 9-10 month span depending on year.
The problem inhibiting some of the analysis is that most often, last years spreadsheets do not get filled out after PPR.......and I'm going to conclude the reason for that is that Visa was issued, and packing was more important than forum posting, as the waiting game is over. This is a common trend for all spreadsheets of last year, and logically it makes sense.
So given that, the conclusion is fairly simple.....in most cases the Manila VO gives PPR approximately 1-2 months after sponsorship approval, and roughly 50% have documented Visa issued date of 2 months after PPR, where the others (that have been assumed to get Visa quickly) are assumed to have Visa in a matter of weeks.
We can go further to assume then that processing time, on average, for Manila Visa office is 2 to 4 months.
I know this is a lot of assumptions, but they are logically based where assumed, with roughly half based on facts.
Just my 2 cents
