What is network diff? I want to learn that to feel comfortable and be capable to do the math by myself. Now I can see that the hash is 6.12P. What is the relationship with the hp and the network diff? Why u say that if we have more hp in your pool would decrease this time.

EDIT:
If I have started yesterday with 54 TH, so only after those 80 days that I will be in my max performance?
