Apparently , the activity changes every 1210000 units of the UNIX timestamp.

This equates to 14 days , 6 minutes , 40 seconds.

This means , after 3026 2 week periods , you would expect to gain 42364 activity.

But no , you would get only 42350 activity.

TLDR; Every 116 years you will lose out on 14 activity. Sad right ?

FAQs of the Activity system
(All of these can be found stickied in the Meta , but just in case)

Q : How is activity calculated ?

The activity number is determined in this way:
time = number of two-week periods in which you've posted since your registration
activity = min(time * 14, posts)

Q : Help ! My activity (or rank) has not activated yet , even though I have sufficient posts and have posted in sufficient time periods !

Outdated. It occasionally takes much longer to update, but still an hour on average
