I reckon Immitracker only gives a general and non-specific trend on the basis of historical and current data self-reported by folks of a wide variety of backgrounds using that system. Since each case is unique, I would rather say any timeline you see on that tracker will likely not be a good reference for you to estimate your PPR date.
Also, the progress bar in your account doesn't take into account the specific situation of your application, so don't rely on it.
If you have a lot of patience, you can wait out the entire process. You can order CBSA notes if you aspire to get more info.
