This is the summary of my journey to the Galactic Core in my Federal Dropship. However, I found after selling my data that my credit balance had increased by 99,006,260 credits, whilst my profits from exploration on the statistics tab had increased by 105,677,755 credits, so I'm not sure how much I really made but will go with the credit balance.
Side notes: I left for Sgr A* on 4th July 3301 with 1 system unsold (worth 6901 credits, a brown dwarf system with a WISE catalogue number less than 20LY from Sol). I did not sustain either hull or module damage during the trip (my fuel scooping technique is very risk-averse) but with wear & tear down to 0%, the cost to repair my dropship was 198144 credits (done after taking these screenshots).
Exploration Credits for this trip: 99 million credits
Total Exploration Credits after this trip: 214.5 million credits
