hermaphrodite's a series of questions?

So I heard that feminized seeds have more of a tendincy to hermie. My problem here is I bought a shit load of them. My plan was to start them inside then move them outside to flower. But then i read stressing them in this way will produce hermie's. I also read that the hermie traits could show up at anytime during the flowering process. So here are the questions

1. At what percentage would you say a feminized seed has of hermieing 50/50?

2. If I use dutch master reverse and pick the sacks will the products potency decrease just because of the hermie traits? Would it use of some of its potency just creating the male pods?

3. Once a male sac appears how long do i have before the sac opens and pollenates the female flowers?

4. Do you think it would be worth while to take a clone from each plant and flower inside? Or do you think this would be even more unneeded stess?

I wouldn't worry too much, I had bagseed that was slightly herm, each of two plants had one node with pods. It was deep into flowering, so I could tell easily and plucked 'em before they opened up, although I did get a couple ripe seeds. But the quality was still superb and I didn't notice anything wrong with anything, except that I got two females out of two plants
