multiplying by .5 then by 2 is redundant. Since you're using all multiplication, there is no order of operations and the two will cancel each other out. You're basically multiplying 1/2 x 2= 2/2 = 1 and anything multiplied by 1 is itself.

What you're really trying to figure out is your work percentages.
The two of you together do a total 55 hours a week. Of that you do 15 and he does 40
That means you do 27.3% of the work for income and he does 72.7% of the work for income.

Therefore when you reverse it, you should be doing 72.7% of the home labor and he should be doing 27.3% of it.
Therefore-
Labor for Sunny should be: 0.727x355=258.085
and
Labor for Husband is: 0.273x355=96.915

I feel though the creation of all this is just going to lead to more problems because you are going to have weeks where people are going to do more than others than have more arguments about people making up points and it's just going to get even more ###$ up from there. So my solution is just don't be lazy, do what work you can when you're able to, and work together... it's a marriage, not a competition.

Seeing as your husband works more hours than you, you could figure out between you what chores he has time for before/ after work, at weekends etc, then make those his responsibility.

For example, my bf does the washing up, mowing the lawn and tidies his things. I do just about everything else around the house. He works twice as many hours as I do, and it works out that I can get the housework done while he is still at work (small house, with only the 2 of us), so that seems fair to me.

We don't have many arguments about the housework, I don't nag him to tidy up, for example, but if he doesn't put his clothes in the laundry basket, they don't get washed!
