The definitive explanation of how activity works!

[Liam W]

I've posted this in so many threads now...

So, basically, the formula for the activity value is this:

Code:

time = number of 2 week periods in which you posted
activity = min(time*14, posts)

So, lets break this down.

Code:

time = number of 2 week periods in which you posted

This basically means what it says. If you've been registered for one week, then this will be 1. If you've been registered for three weeks and posted on the first day of registration and again today, then it will be 2.

If you've been registered for one year (lets say you registered on the 1st January 2013 and today is the 1st January 2014), and you only posted on the 1st January, 10th January, 23rd March, 15 April, 18 April and the 23rd December, your time value would be 4, because you posted for 4 two-week periods.

Code:

activity = min(time*14, posts)

This basically says that your activity value is the smaller value of your time value multiplied by 14, and your post count. So, if your time value is 2, then your time*14 value would be 28. If your post count was 30, your activity value would be 28. If your post count was 20, your activity value would be 20.

I hope this explains it to some people

How many times a month is this number calculated?

How many times a month is this number calculated?

It's re-checked every half an hour I believe (it could change whenever your post count changes).

Thanks. This makes things clear.

What I didn't get at first is you get 14 more of activity (if your post count is higher of equal to your time) as soon as you post on the first day of a 2-week period

Exemple I registered January 13 my activity is one after the first post and 14 after 14posts then 14 after 15posts and more until Jannuary 27 where it becomes 28 if I made 28posts or more

It can be quite hard to get your head around...

If, on the 2nd two week period, you have more than 28 posts, then your activity will increase rapidly to 28 (an extra 14 points).

The confusion arises when you have a lower post count. Say you have 13 posts, on your first 2 week period. Your activity will be 13 (lower than 1*14). On the 2nd two week period, your activity won't change. If your post count was 15, then your activity would be 14. On the 2nd two week period, it would increase to 15.

It can be quite confusing

Another thing to think of, if the activity value doesn't divide by 14, then it's going off post count (your activity is higher than your post count). If it is divisible by 14, then your post count is higher than your number of 2 week periods. I've clearly had 10 two week periods I posted (140/14)...

No threads specifically to explain it though, just asking how.

I read about it so many times @bitcointalk.
I even explained it to 10 persons around science last year.

Anyway your tutorial is very nice and I am really glad you ve done it!

Cheers!

What I see when reading this guide (don't worry I was a n00b once too,   ):

If you need an explanation for the post count thing, here you go!

The definitive explanation of how post counts work!

Really simply put, the formula for calculating post counts is:

Code:

/*
The definitive formula of the calculation of post counts
*/
int postCount = 0;
while (postCount < lastPostNumber) 
{
    postCount++;
}
int finalPostCount = postCount - numberOfDeletedPosts;

The value of finalPostCount is the number of posts you have, e.g. your post count.

Breaking it down further for you,

Code:

/*
The definitive formula of the calculation of post counts
*/

This does absolutely nothing.

Code:

int postCount = 0;

This makes the post count start at 0.

Code:

while (postCount < lastPostNumber) 
{
    postCount++;
}

This counts how many posts you have.

Code:

int finalPostCount = postCount - numberOfDeletedPosts;

Well, the previous count wasn't perfect so... We make it perfect!

Voilà, you have your post count.

The definitive explanation of how post counts work!

Too complicated. How about:

If p₀ is your oldest post and p_n is your newest post, then define:

post_count_at(p₀) := 1
post_count_at(p_i) := post_count_at(p_i-1) + 1 if 0 < i <= n

Then your post count is post_count_at(p_n).

Is this a recent development?  Used to be much simpler iirc.

[Pony789]

So if I made more than 28 posts in a two week period I'll ever more messages than Activity?

You can get at most 14 activity in 2 weeks, so if you made more than 14 posts in a two week period, your post count will be larger than your activity.

It hasn't been changed for at least 4 months.
But I have no idea how activity is calculated before I joined bitcointalk lol.

Let me see if I understand this correctly.

In order to maximize your activity count, you need to make one post a day OR 14 posts exactly every two weeks.

No... to be active you have to log in at least once every two weeks. To maximize activity, you must constantly be active (log in at lease once every two weeks) AND have a post count greater than or equal to the number of days you have been active.

It doesn't matter when you get your posts. You could for example log in every two weeks for two years and not post anything, then post 730 times in  a week. This would put your post count and activity at 730.

Oh I thought you needed to post every 2weeks period, you actually only need to log in

I can't find where is the next activity change

Probably should be stickied. I don't remember reading it anywhere in the help.

Indeed and people are asking about it once for a two days
anyway they just do not use search and they do not find what truely was mentioned so many times.
