When you text a recruit to get information about how much they care about different areas such as location or school prestige, does it automatically also tell them about your school and increase your favorability? And if so, is it worthwhile to repeat this action every week with recruits I really want? (So tell them about my location a second time a week later?

No when you get an answer in these areas it lets you know how important a particular thing is to a recruit so you know a) if your school is a good fit for what is important to him and b) what the most important thing is to pitch to him when you do your home visit.

Hit each category. Repeating does no good but getting the info is vital for the reason Gary mentioned.
