FTL Autorewards Analysis
In February 2015, I did a deep analysis of the rewards you get, depending on if you win, lose, or flee a battle or choice presented to you (they're called Autorewards in the game files).
This info is best seen in the pretty FTL-style fonts of the FTL Wiki, where I crafted a very long analysis. I carefully entered 498 encounters into a database and compared it to the XML-style game files of which types of rewards the game said were due (Low to High of Standard, Fuel, etc. versus the eight game levels a.k.a. sectors).
Check it out. You're welcome!
