And by extension Beginner combat.

For each beginner combat kill, reward the player with around 250 credits and then a 2000 credit bonus for each set completed

For advanced combat, give 750 credits per kill and a 5000cr bonus for each set.

Also increase the combat and port rewards to 600/450/450 for advanced combat (something less for beginner) at the end of each set so that players reach combat 3 & 4 faster and have an immediate gratification of earning a lot of credits along the way- relatively speaking.
