Compact BigReactor design, help needed.

I'm building a 5x5x5 reactor with a 3x3x3 reaction chamber, and I used the BigReactor simulator to see how the results would be, but I don't know very well what all the numbers mean on the page so if someone could explain in details and tell me if my reactor is good in terms of RF per yellorium ingots. I'd highly appreciate. The reactor design is right here
