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

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

time = number of 2 week periods in which you posted

activity = min(time*14, posts)

So, lets break this down.

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.

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
