I created a spreadsheet with the calculation for XP/hr and Profit/hr of goods sold at the market. The assumption that 1 day goods are 22 hours, and 2 day goods are 46 hours. (If anyone can confirm if 2 day goods are either 46 hours or 44 hours, please let me know!)
Google Docs: Empire Story Goods Spreadsheet
The spreadsheet is split into 4 tabs:
Alphabetical
Sell Time
XP per Hour
Profit per Hour
Naturally the calculations at the shorter-timed goods are going to be slightly off due to time spent tapping to book the order. So take the dramatically larger number with a reasonable margin of error.
Please correct me if you find any typo or miscalculation!
