Nevermind, I found the answer to what I was looking for:
Wait, to be clear, the importnat thing about activity is that you have to make AT LEAST 1 POST in each 2 week period, and then MICRO's statement is true. You cannot make 1 post, wait 1 year, and then get hundreds of activity as you keep posting. You have to post in a 2 week period of that to count for your max activity. For instance if you post 1 time, wait 2 weeks, make 1 more post, then wait 2 weeks, your max activity will be 28. Then for the next 2 week period, you will get another "14 activity max" period so you can keep posting up to 14 x 3 which is 42.
This activity thing is almost as complicated as the blockchain. xD
