It all depends on how complicated is your case, are you inland or outlander, cic or fsw, pnp, combinations of these, assessing officer assigned etc etc.
Cic will try to get your file processed within 6 months, but than again you will see applicants who have crossed that deadline and are still waiting. Surprisingly you will also find applicants who have received ppr within a month.
Bottom line is, just submit your application? Get back to your normal life and find some time to visit mycic and this forum to get updates on whats in the abyss of long wait for pr. Blow off some steam here!!!!
