They should make upgrade in you account rank going by multiples of 14 activity, or update activity every 15 days.
Kind of sucks being caped at 56 activity in Junior status, or as full member with 238. This makes the real time to get until a given status around 14 days longer.
If then, the activity required may probably just be increased to 70 and 252 (multiples of 14).
For your information, theymos did increase the activity requirements from time to time.
When the activity system was first set up, you just need 200 and 400 activity to be a Sr. Member and a Hero Member
