Of course it is a good idea to be certain to actually meet the PR Residency Obligation, so to the extent a PR is not confident they are completely and accurately reporting all dates of exit from Canada and all dates entering Canada, it is a good idea to wait long enough to cover any doubts . . .
but completely and accurately reporting the travel dates is by far more important.
I seem to be among a small minority in the forum who do not think a buffer makes much difference in how it goes in processing a PR card application. Other factors have a lot, lot more influence in:
(1) whether the application is subject to non-routine processing and consequently it takes significantly longer than the currently posted processing times (currently 75 days), and
(2) whether IRCC challenges the number of days credit the PR claims
Ten or thirty or sixty days more than two years is still way less than living in Canada even half the time. So the more important, more influential factors relate to whether there is cause to doubt the completeness or accuracy of the PR's report of travel history.
Among the more salient factors looming much larger than buffer days:
-- accuracy of information provided by the PR (inconsistencies, discrepancies, omissions, or incongruities will, of course, elevate the risk of further inquiry or even formal investigation)
-- extent to which it is clear (or not) the PR is currently PERMANENTLY settled in Canada (typically as seen in the PR's pattern of work, address, and travel history)
-- travel outside Canada after applying inconsistent with continuing to maintain a permanent home in Canada
-- any history of issues or potential inadmissibility concerns
Note: it appears you have history which seems likely to invite increased scrutiny. Hard to say what effect, if any, this will have on how long it takes to get a new PR card. Obviously, if you leave Canada for an extended period of time after making the PR card application that is likely to significantly increase the risk of non-routine complex case processing or possibly even skepticism about your version of days in Canada.
