It does, I get it - and I stand by the calculations. Your average seasonal recreational boater can not log the days at sea requirement, not realistically.
Getting home after a days work and sailing until dead dark doesn't get four hours, so you get 2 days a week, 6 or so months a year.
Maybe that's the intent of the requirement, if so fine by me. I'm satisfied with meeting my own knowledge and experience standards. I'd like to see a recreational boaters licence tho - it would help with insurance.
