I was playing around with the money/xp slider over the last few days and when i analyzed the missions i didn't see much of a difference over the price that the missions paid for either setting. Other then differences in distances i thought that the money seemed almost the same, so heres what i did.
I needed a place where i knew they would give me the exact same mission as many times as i asked for it. I rerolled a ner character and went to the newb terminals to try it. I set difficulty to 50% money to max and all other to the middle. result a mission which gave me 102 creds and 19 xp. Kept all the settings the same except switched to full XP instead of money. the results a mission which gave me 102 creds and 19 xp the EXACT same as with full money. Now maybe this is like this because of the fact it was the newb terminals but seems to be weird they would have a different set of rules for all the terminals.
This leads me to wonder if ANY of the sliders actually work. The only difference i have found in changing slider settings is the type of missions you predominantly get. ie assassination find item find person....
