I'll see what this comes out with it. I really prefer Far Trader to the T20 system, something about it being based on actual econmic theory
Saanath has Broker at 16
His Market Anaylst skill will come into effect when the cargo is sold.
Anyway:
Shirgegge has a Class B Starport, meaning the DC to find Speculative Cargo for sale is 20, modifed down to 13 by it's population.
Saanath gets a 1 on that check, but rather than automatic failure I'll rule that he finds only 1 potential cargo
Rolling for type, 78 = Statuary
Base Price is 250,000 credits for a lot of 7dt
Purchase Modifers:
Final Price would be modifed down by -2 as they are being bought on a non-industrial world
No Final Price Modifers apply at point of sale, as Missarge (nor anywhere else you are likely to be going with this) is either Rich or Industrial
Actual Value:
Let's see what Saanath can do to the final value
29 = +3 bonus (which is not quite the way it says in the book, but)
Net +1 to the Actual Value
Market Anaylst:
1st die = DC15
Success, one of the three dies on the Actual Value table is a 3
2nd die = DC30
Success, second die = 5
Total so far is 9 (3+5+1)
At this point Saanath knows that the final die will be between 1 and 6, in the worst case scenario (a 1 ) the cargo will sell for exactly what you paid for it, in the best case scenario a (6) it will sell for 150% of the purchase price
So with 250,000 for 7dt you can buy two lots on which you are guaranteed to break even - however, you will need to find 500,000 to do so.
