I'm tired. how do imperial rank grind????!

With colonization and stuff, the Ngalinn, Mainani, Aitvas loop is completely broken and doesn't work, or is inefficient and confusing. So, I've been searching for other ways. The problem being that every single source I can find on YT, here, or the official forums, all either don't work/are outdated, are confusing or boring, or are extremely time-consuming.

The most effective thing I've found was going around Achenar and shoveling money into the various stations. That gave a good two ranks (Squire > Lord) but after like two circles of the system, all of the stations give like two or three donation missions each refresh which really slows down the grind.

This grind area is confusing and doesn't seem to work all that well, considering I got to the first station and there were 0 courier delivery missions.

This one is good... for ONE go. Immediately after, it completely gave up on giving me any of the right missions.

Stacking massacres is time consuming and doesn't offer that much rep in the same amount of time as the Achenar donation loop, at least short-term.

Does anyone have any other options...? Money isn't an issue, but I really just want my cutter already.

p.s. i am not a newcomer, I've been playing since like 2019, i just don't have the rank grind done on this CMDR (it's fairly new, part of a return to this game I started a month or two ago, but has an FC and all that), and the loop I've been doing for all this time just doesn't work anymore.
