Is saying "worked an average of 30 hours per week" a red flag?

I realise that Canada's benchmark of 30 hours per week is v. specific to IRCC. I initially worked part-time for an employer (20 hours per week) and then it went up to 40. They put "worked an average of 30 hours per week" in my letter. I'm worried IRCC will flag this because it's too exact.
