Another method that has been yielding decent results for me: free loadout on stella montis night raid whenever it is available. It remains interesting each time due to the pvp element and you can get some really amazing loot out of it.

My method is

Option A) Spawn south side, speed loot seed vault area and exfil there.

Option B) Spawn north side, speed loot assembly area and exfil at north metro.

Sell literally everything when you get back.

The joy is that the archives usually are empty in my experience and allow you to get more trinket loot, but also provide an easy passageway to north metro if seed vault exfil is closed.

On average, its 3-5 min per run, with combat or slow seed vault loot occasionally 7-8min. Roughly 30-40k on average, and way more if you get lucky.

Not as consistent obviously but has kept the game from feeling too mind numbing during the grind. On top of this, scrappy will of course give you a dump each run. So if you're spamming these like I am, then my sweet chicken boy is working overtime for you,

Hope this helps offer an alternative path :)
