Since the same questions about activity are re-asked over and over, i will try here to simplify things.
I will start with definition then I will illustrate it with examples :
-Activity : activity is limited to 14 for every period considering that you made at least one post in it.
Activity increases with the number of posts you made but it will not exceed 14 even if you made more than 14 posts in a period.
-Potential activity : it is the activity that you have but you didn't claim because the number of posts you made is less than 14 per period (for 1 period or more)
You can calculate it by multiplying 14 with n (n is the number of periods you made at least 1 post in it).
Example 1 : ep1 :
- Newbie1kenobi has joined today the forums and he made 1 post in period1 so he will have in his profile 1 post - 1 activity (and he has the right to get up to 14 activity which we called potential activity)
- He later added 3 posts in period1: so it shows 4 posts - 4 activity (he can still claim the remaining 10 potential activity).
- He made later a total of 20 posts in period1 : so it will shows 20 posts - 14 activities.
Example 1: ep2 :
- Newbie1kenobi made only 1 post in period2 so in his profile he will have directly : 21 posts - 21 activity.
If you will ask why he jumped directly from 14 to 21 then the answer is simple and logic.
Since he made 1 post in period2 he claimed another 14 activity which means he have the right to reach a total of 28 activity (which we called potential activity). Now considering 1 post = 1 activity and he has posts (20) > his activity (14), his activity will jump directly to the number of posts he made without passing 28 (his potential activity).
Now at the end of period2, he has : 21 posts - 21 activity (and 28 potential activity).
Example 1 : ep3 :
Newbie1kenobi didn't post in period3, then his posts, activity and potential activity remain unchanged. He lost 14 days.
Example 1 : ep4 :
Newbie1kenobi didn't connect in period4 and didn't make a post.
A staff member found a trashy topic in the forums and throw it to the garbage. Newbie1kenobi made the mistake of making his unique post in period2 in that trashed topic.
He lost his post for period2 (actually all his posts in period2 since he has only 1) then he will lose the 14 (potential)activity dedicated for period2.
Newbie1kenobi has at the end of period4 : 20 posts - 14 activity (and 14 potential activity).
Example 1 : ep5 :
Newbie1kenobi joined a signature campaign and spammed the forums with 100 posts in period5. He will have then : 120 posts - 28 activity - 28 potential activity.
Remember that his (potential)activity cannot increases more than 14 per period regardless the number of posts he made.
Example 1 : ep6 :
Newbie1kenobi is banned from the forums for making non constructive spammy posts.
