Yeah, as Archer says, it’s a godforsaken mess.
CCP replaced what was a functional standing transaction log with this mess a few years ago and it’s completely unusable is many cases, or it just lies to you.
The formulae that CCP gives us for standing from their support page (https://support.eveonline.com/hc/en-us/articles/203217152-Standings) is now also totally useless to us because the value “i” used to be displayed by the standing transaction log, and now it is obfsucated from the player.
Sorry to say that you basically can’t trust the standings window at all.
