Section 5.1 on page 7 states;
"For persons who have been permanent residents of Canada for more than five years, the only five-year period that can be considered in calculating whether an applicant has met the residency obligation is the one immediately before the application is received in the visa office. A28(2)(b)(ii) precludes a visa officer from examining any period other than the most recent five-year period immediately before the date of receipt of the application. Even if a person had resided away from Canada for many years, but returned to Canada and resided there for a minimum of 730 days during the last five years, that person would comply with the residency obligation and remain a permanent resident. An officer is not permitted to consider just any five-year period in the applicant's past, but must always assess the most recent five-year period preceding the receipt of the application"
If this period is your only concern, you need not worry. Just fill out and send the RQ.
YOU ARE THE MAN
