There is a dusting schedule on the site somewhere. I will see if I can find it and link it to this thread. I don't know that there is an "end all be all" dusting rotation. I do 1 day on one day off dustings. Like this

Monday -Cal w/ D3
Tuesday -No Dusting
Wednesday - Cal w/ D3
Thursday - No Dusting
Friday - Cal w/D3
Saturday - Multi Vitamin
Sunday - No Dusting
