I never believed in that theory. But I believe in a different version of it. It's not that every applicant is different. It's just that every visa office and visa officer officer is different. If you end up with a slow visa office or visa officer nothing one can doAnd Immitracker is showing irrational trend as ever, no explanation why an applicant got PPR today in 130 days and another in 500 plus days ( without being in SS) from LVO and they are distributing plenty of files now to other VOs after sitting on them for a good 6 to 7 months.
Please don't quote how one applicant is different from other because it's BS.
