---------
A = min (p , 14*n)in which
A = Activity
p = post count,
n = number of two-week activity periods in which the user has made at least 1 post.
Case A: someone makes exactly 1 post per day and the first post is made in the first day of the activity period. Day 1: p=1, n=1 ---> A=1 (The first day of the first period)
Day 2: p=2, n=1 ---> A=2
...
...
...
Day 14: p=14, n=1 ---> A=14
Day 15: p=15, n=2 ---> A=15 (The first day of the second period)
Day 16: p=16, n=2 ---> A=16
...
...
...
Day 28: p=28, n=2 ---> A=28
Day 29: p=29, n=3 ---> A=29 (The first day of the third period)
Day 30: p=30, n=3 ---> A=30
It took 30 days to become a junior member
Case B: someone makes exactly 1 post per day and the first post is made in the last day of the activity period. Day 1: p=1, n=1 ---> A=1 (The last day of the first period)
Day 2: p=2, n=2 ---> A=2 (The first day of the second period)
Day 3: p=3, n=2 ---> A=3
...
...
...
Day 14: p=14, n=2 ---> A=14
Day 15: p=15, n=2 ---> A=15
Day 16: p=16, n=3 ---> A=16 (The first day of the third period)
Day 17: p=17, n=3 ---> A=17
...
...
...
Day 28: p=28, n=3 ---> A=28
Day 29: p=29, n=3 ---> A=29
Day 30: p=30, n=4 ---> A=30 (The first day of the fourth period)
It took 30 days to become a junior member
In both cases, it took 30 days to become a junior member.
Since I don't want to bump the other topic, I reply to your post in that topic here.
"If a brand new member posts everyday, after how many days will he get the Jr Member rank?"
- Answer: At least 29 days. Posting at least once in the last day of one of the 14 days period (+14 potential activity) and posting at least once in the next 2 periods (+14 x 2 potential activity) = total of 42 potential activity. Then, making at least 30 posts and getting 1 merit.
No, At least 16 days.
Below is what needed to do.
1. Register to the forum at last day of a two-week activity period and make at least 1 post in that day.
2. Make at least 1 post in the period 2.
3. Make 28 posts at first day of period 3. (Because 2 posts have been already made)
