"(the starting level; this tier does not scale during a mission as higher level enemies spawn)"

I think this is wrong. After playing a while on Lua i got 1000 credits, 3000 credits, from then on only tier 2 rewards (Tower 2/3, 1500+ credits, Provoked, Spare Parts, etc). So the first reward is clearly tier 1, the second could be either, but by the third extractor it has switched to tier 2. I did not however get any tier 3 rewards, but maybe i wasn't there for long enough.
