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)
the activity one
the time one i think is every 2 weeks the unix time stamp or something like that. every 2 weeks you can climb on grades (i think)
but the activity one is tricky.. activity = min?? or does it require a number of post counts to get ranks??
https://bitcointalksearch.org/topic/forum-rankspositionsbadges-what-do-those-shiny-coins-under-my-name-mean-178608 is best thread about activity.
Yes every "two-week periods in which you've posted since your registration" you can gain a activity level (One level is more then one activity point).
It does require 14 posts to gain a level. Again that is per every two weeks. You can post more and it is ok but 14 post is min to gain activity level every 2 weeks.
i actually came from that link you share before posting this.
ok here is the thing, i was brand new 4hours 30minutes ago (registered 2 days ago) pstarted posting my first yesterday] then i logged off
today i come, explore the forum cause i want to learn about bitcoins, asked questions and posted on many threads.
4hours 30minutes later, i am newbie with 18 activity.. if i continue to stay on the forum and post (not spam of course) will my level change from newbie to err jr member i think comes next, today itself or in 2 weeks??
also,
Member: Activity: 15,
Full Member: Activity: 60,
Sr. Member: Activity: 200,
15 to 60 makes 45 activity, does that require 3 x 2 weeks or it might happen in a week/ day/ days itself?? ( since i explore bitcoins, i post a lot [[again i am not spamming anywhere]] i am just here to learn and understand bitcoins...
then from 60 to 200 how much time that is going to take?
i saw many profiles not with 15activities and registered since 5months ago or something..
also many profiles registered february but managed to be junior with 56 activity, will their activity continue to grow till 60 or they will have to wait for the next 2weeks for it to happen.. i saw yesterday was the activity update..
i am very sorry if i am troubling someone, like i said, just here to learn
I see no issue at all. Yesterday activity was updated, due to 2-week period ending, so your activity went up...then you logged in today, you started posting and so you started gaining more activity. Activity can increase of only 14 pts every 2 weeks.
To know when the next update came, I suggest you looking into this topic: https://bitcointalksearch.org/topic/til-activity-does-not-work-on-precisely-2-week-intervals-interval-timings-582736
