I can’t be certain in this case, but the usual suspects are not being connected to as many servers (e.g. not scraping some because of robots.txt settings), delays in scraping the stats, or excluding some servers consciously because their stats are deemed a bit suspicious.
It seems like the other two tools only report about 49k MAU, any idea why?
on fediverse observer, you need to switch to daily stats not monthly stats, right now it says 53,225 MAU for March 13th as the latest datapoint

fedidb is probably doing something similar, just showing the average for the whole month, instead of the current day
