Have fun and I hope you find it useful."
You should make a private copy of this sheet and change all the values highlighted in green to match your own game progress.
1) Enter the number of vendors to sell 'full loads' (based vendor size), and it will calculate the production levels to produce enough units to sell AND the units consumed for their production. E.g., if you want to sell 2 loads (3 vendors) and your Vendor Size is 12, it will calculate the levels to produce 36 units.
2) Enter the number of units required for an expedition and how many hours you want to take, and it will calculate the production levels to produce those units AND units consumed for their production.
3) There are also some minor features.
