How you manage the screens results?

Hello Pat!
I would like to ask regarding the screens on Marketsmith and their manage.
I know that you focus on these screens: Bill Screen, 40% Earnings/top 40, 45% Average 2 Qrt. and Master SCN 1-10. I suppose that you consolidate the results on one List. This list surely has a lot of names, maybe a hundred. Do you check each stock in order to find the best setups?
When you finally get the Key List, What are your criterias to set a buy stop?. I mean, the Key list of today Monday 8th, it has 24 names with 17 of them with a trigger price; Let's suppose that all of them trigger the buy price, do you have a buy stop in all of them?. I suppose that not but I prefer to confirm. My assumption is considering that could be difficult to manage a portfolio of 17 names.
Which are your main criteria to set up a buy stop on the names detailed on the key list?.
Thanks!
Cristian
