This. I never thought I would get 500+ loot, ever.
Even though 1k Kerbs do happen, they do not happen as often as Feffox, Proteron, Atrox, spiders etc...
I seriously doubt that someone who is cycling a whole lot of peds on decent size mobs wont get an Uber.
In years prior to 2016/17 I used to hunt stuff like berys, daikibas, molisk, argonauts, and other tiny stuff, and I was happy if i got a global a week, and was hoping and hoping and hoping for a HOF loot, but none came.
Then, I saved up a bit, bought myself some decent-ish gear, and first upgraded to Feffoid sometime in 2016, got 2 hofs, 733 and 788 ped. This was done mostly in the cave north of PA with Manta K3 + Koroma.
After that I switched to Atrox @ Jurra Plateu, and got my first uber 1119 PED Atrox, used Adj Musca + 5A plates
and Isis CB19.
And recently I upgraded again, got myself a R150 Assassin and I switched to Feffox, started cycling ~5000 ped a week, and got my second uber 1252 PED on them.
I am lvl 45 blp hit / 41 blp dmg, 153hp.
