Wonderful tool, the idea is great!

A) The keywords mentioned for the ranking refer to the fact that I can track them daily. Can I "try out" more keywords and see how the ranking currently behaves? So a real-time assessment? Is the restriction to e.g. 5 keywords in Tier 1 only related to the ongoing tracking?

B) And what exactly do I use the program for? How can I improve my ranking with the program?
