Yes! Your daily post will be increasing by normally there activity change which only will change in every two weeks, mean within two weeks you got 14 activity. Its so simple idea. For more details check out posy about this.
It's also important to note that you get 1 activity point per day and in order to keep getting that daily you need to post once every 2 weeks. The points are handed out 14 at a time so every two weeks like you say. I just though it was easier to mention that it grows 1 point per day. So you can see an account with over 300 activity is over a year old most likely. Sometimes people don't post every single 2 weeks and lose some activity.
