As our process ended in less than 11 months going through the Mexico VO, I feel there's a big misunderstanding on this forum in regards to the processing times. The standard time is 12 months, if one out of 10 applications is processed in 6 months, that's their way of averaging out the process. For example if they process one application in 12 months and another one in 6 months, when you average that out, it gives you 9 months, so they can say they lowered the average time.
On the other hand, if you read the fine print on the processing time you would know that they only "aim to process 80% of the applications within the 12 months" and the last time they reported actual data they indicated that only 73% of the applications were processed within 12 months (so they are informing that they are below the service standard). In the end, you cannot blame the local visa office entirely, every application is different, it doesn't matter if you sent yours the same day as your neighbour, they are processed differently
Finally, Mexico VO is known to be slow and I was fully expecting our application to go the full year and possibly more, but you have to consider that they process the applications for several Latin-american countries. This is a process that used to take 24 months and some people here have been waiting for 6 months and are already losing patience, just relax enjoy the weather and when you least expect it, you will get the good news, I wish everyone good luck
That's just my opinion
