No, Once BG process started then only they will do R10 and A11.2 validations. Based on majority of the applicants, it has been understood that BG process will be Not applicable once R10 and A11.2 is done. Thereafter your application will be transferred to LVO for final decision. Once officer starts review your application they will change BG again to In Progress. Once you see the status, then you can assume that your PPR is around.
There are many surprises during the process. Some applicants reported that without any BG changes they have received their PPR. By having said that, we never know what will happen to our application. For some reason, if status is struck for a while then you can order GCMS notes to understand the situation of your application.
All the best with the rest of the process.
