I might be able to answer my own question ;-)
dpenabill says in another topic:
"As Politren and Diplomatru have observed, the full period considered is limited to the five years immediately prior to the date of applying.
While Rusty53's observation is correct on the key element that the maximum credit for pre-landing time is 365 days, thus only two years of presence prior to landing counts, that two years of presence can occur in a span of up to three years. In other words, unlike how it was under the previous 3/4 rule, in which every day absent in the two years prior to landing meant having to be present two more days after landing before qualifying, the proposed 3/5 rule will not in effect penalize students or temporary workers for occasional absences in the two to three years prior to landing.
Obvious example: for a student who was in Canada three years (or close to three years) prior to landing, and who went to home country for total of 60 days during the two years prior to landing and becoming a PR:
-- under old 3/4 rule, the absolute soonest this person could qualify (per physical presence rule) would be 2 years and 120 days after landing, and add (approximately, since actual arithmetic would depend on precise dates of absence) two more days for each day absent after landing and before applying
-- under proposed 3/5 rule, the soonest this person could qualify would be exactly 2 years after landing, and add only one day more for each day absent after landing
Overall, old 3/4 pre-landing rule involved adding two days more presence after landing for each day absent in the two years prior to landing (up to not qualifying for any credit for pre-landing time), whereas no additional days need to be added after landing despite absences prior to landing, for up to a year of absences within the preceding three years (but still within five years of the date of applying).
This is a rather generous, liberal path to citizenship for those who initially come to Canada with temporary status."
Which would make my calculation 1 correct, because absences prior to becoming a PR do not count as a whole as long as you've made the 365 days (half days!). As soon as you have 365 days as a TR, you only have to make up for absences from the time you became a PR. So technically if I became a PR in April 2014, I should be able to apply for citizenship in April 2016 + additional days for every day absent as PR (in my case 100 days).
Correct? If new law passes, that is.
