I had like 1 year and a half of part-time working experiences in NOC B and the total hours accumulated has almost reached 1560hrs，but the question is that my hours per week is quite unstable，sometimes more than 20hrs a week and sometimes only like 12 or 13hours a week，so will those weeks that i worked under 15hrs/week be eligible for counting as my part time experiences？Or do they just simply add the salary together and divided by salary per hour to get the hours？ Because it is confusing on CIC website，showing that full-time：30hrs/week part-time：15hrs/week （1560hrs）for 2 years. Thanks if someone could answer the quesiton for me please！！
