How to calculate mining XPM profit?

I am using the recommended jhPrimeminer v4.0 by rdebourbon on

  1. Is there any other settings that I should adjust besides the username and password? Or should I just run it using default?
  2. How do I calculate my profit?
  3. On the website “Share value/h”, how do I use that to calculate how many XPM I get per day?
  4. jhPrimeminer, how do I tell how fast I am mining? And, how to use that and compare to ypool’s “share value/h”?
  5. Is there a profit calculator?
