You are right, but you missed the main point.What you're not taking into account is the serious nature of the subject matter. Getting PR is not a trip to a local restaurant. Many people consider this a life changing event and their lives highly depend on the outcome.
While you're right that we were given a time frame, the seriousness of the situation and a huge inequality in a way how these applications are processed, make it tough to handle.
It's not that others are getting PPRs in 2-3 months that is frustrating but the fact that you're 4 months since AOR with your application being untouched and you still have the same chances of rejection as you did when you were 30 days after AOR while others are getting PPRs in these 2-3 months.
You said that everyone's situation is true and you're right. A lot depends on the recommendation of an analyst. But in order for an analyst to make a recommendation, he/she firstly needs to look at your application, which means that in order for the situation to become different, they have at least start doing assessments.
You have the same aor as another person does. After 60 days his/her eligibility is marked as "RR". Yours is not even started. 60 days more he is in process of fixing the issue and your eligibility is still not even started. Then 30 days later your eligibility finally is recommended as "RR". And now your path to PR starts from this point, which is 5 months after AOR, while another person with the same issue is 3 months ahead of you in fixing his "RR".
Ordering notes around the time of eligibility review can save the application from being rejected if you see the problem and react to it on time.
