This helps alot I think what she did was figured it at a 40 hour a week job. That would put me at 2080 hours in a year leaving it at 24% t/s ratio.
My actual working hours with kids was 2,428 hours, so that would be 28% correct? If I'm reading your link correctly, I can add on at least an hour a day for cleaning, prepping, paperwork. If I do that, since I worked 243 days, that would be another 243 hours. So that would increase my t/s % to 30%. Am I figuring it right?
