Not offhand, I haven’t really payed any attention to it for a long time now, I do know there’s a couple missions in each arc that has unavoidable ship kills and the amount of standing loss for them is very small. I’ve found it’s best to just not waste time with them, as in trying to get around not killing them.
There are a few different info guides available, I personally just use Eve Survival for reference.
However @Sentenced_1989 might have more info about it due to recently posting his Epic Arcs Video Guide.
And lastly for @Sharise_Dragonstar
If you want to build up positive standings with all Empire Factions, I suggest checking ‘The Plan’ for more info…
