Comparing your stats to the forum’s oficial stats (
https://bitcointalk.org/index.php?action=stats) there are a few discrepancies:
- Jan and Feb 2017 are inverted between your stat and the official one.
- August and October 2017 are off by 1
- November 2017 is off a few (97 344 vs 97 286 official)
- December 2017 is off quite a bit (191 537 vs 63 756 official)
December’s number of registered users seems a bit small on the official stats, considering that BTC peaked on the 16th of December, so I always wondered if they were correct for December 2017. I've just seen that, oddly enough, they only go up to the 13 of December (clicking the detail on the official Stats), so yours seem coherent with events.
Forum official stats are not available for some reason for 2018.
Can you explain why you are calling your stats alternative? (I guess you scrapped all user profiles to do it).
On forum profiles there is a recent one published this week by

Truth about bitcointalk users 2.0 . He focused on profiles while you've focused on registration dates.
