Now that we have reached the 3,000 days milestone, I'm going to summarize the results of our investigation, 3+ years in the making.
Shout-out to all those who have contributed and made up other lists before.
(Full list by EasyEdward on page 29, ex 3,000 days)
Edit: All these XPs are subject to personal bonus %% sccording to CC levels, XP boosts and "membership badges".
Early day XPs are
1-0
2-47 XPs
3-63
4-84
5-135
6-186
7-261
8-324
9-397
Day 10: 1030 XP = 880 + (10 * 15) (minor +XP day)
11-553
12-636
13-729
14-822
15-925
Starting on day 15, CDP bonus uses this formula:
880 + (# of days * 3)
except on the +XP days, when more points are given, using the formula
880+880 + (# of days * 10).
These +XP days start with 20, 50, 75, 100 days.
Then, every 50 days until 1,000
(confirmed for all but 850 days)
plus 365 + 730 days = one and two years (not three, confirmed)
Then, only each 1,000 days (2,000, 3,000 confirmed)
This is the highest confirmed number:
Day 3,000: 31760 XP = 880 + 880 + (3000 * 10)
