One can move freely to 2k above 2k; the last rows above are not in the game:

"outpost_levels":[20,25,31,37,50,75,100,150,250,350,500,750,1000,1500,2000],"upgrade_costs":{"20":{"gas":17000,"crystal":17000},"25":{"gas":25000,"crystal":25000},"31":{"gas":34000,"crystal":34000},"37":{"gas":45000,"crystal":45000},"50":{"gas":70000,"crystal":70000},"75":{"gas":129000,"crystal":129000},"100":{"gas":200000,"crystal":200000},"150":{"gas":367000,"crystal":367000},"250":{"gas":790000,"crystal":790000},"350":{"gas":1309000,"crystal":1309000},"500":{"gas":2236000,"crystal":2236000},"750":{"gas":4107000,"crystal":4107000},"1000":{"gas":6324000,"crystal":6324000},"1500":{"gas":11618000,"crystal":11618000},"2000":{"gas":17888000,"crystal":17888000}

There's no need for player levels; they're implicit between outpost levels.
