I'm having trouble finding detailed technical information on Insights. Maybe I'm just looking in the wrong places. Here are my questions:(1) How do I visualize my custom user variables in Insights? Everything I've seen seems "pre-canned" and I don't see how to customize.(2) What is the update rate of the dashboard / how often is it receiving new information?(3) Do you have any sense how much data typically is sent out in a 30 day period? I know the answer is "it depends" but do you have any ballpark idea?
