I looked through my spreadsheet that I track standings loss and gain from and here is what I noticed that has been clearing/resetting after I log out and log back in. I re-entered Eve in August this year and have just been grinding the major factions to 5.0 by mission running, so I have a lot of data collected. Currently 5.0 or better on G, A, C and 4.76 on Min.
SOE gains and losses from all factions other than SOE.
Thukker Tribe losses from all but Amarr and Ammatar Mandate.
Minmatar gains from SOE.
