My original assumptions:

- the bigger the jump the higher the premium. Everybody can go 6 parsecs in 6 jumps. Only a few, expensive ships can do 6 parsecs in 1 jump. The passenger pays a premium for the speed since it takes 6 weeks at jump 1 and 1 week at jump 6. The price of the fuel is linear with ship size and max jump distance. It makes sense: with better technology you get better earnings. The difficulty is to get the ship built in a TL 15 starport and it costs more.

- passengers require life support and should, IMHO, more valuable than freight.

It is easier to explain what I find strange about this table with a few examples. They will all collide with the assumptions done before:

- I am a high passenger that wants to go to another hex at distance 3. If I take 3 jump 1 passages I pay 27k. 1 jump 2, 1 jump 1 23k, 1 jump 3 I pay 21k. Thus, if I get a jump 3 I pay less AND I arrive earlier. (breaking the first assumption).

- There is written that basic passage can also go in the cargo bay taking 2 tons per passenger. That space is better invested with just cargo (any jump distance). For example, basic, jump 2 is 3k. Freight, (per ton) is 1.6k (x2) = 3.2k. Cargo is better. This is even more relevant at jump 6. In fact, considering that every stateroom takes 4 tons of hull, we can say that freight, at jump 6, pays almost (32k*4 = 128k) as much as middle passage (130k)! In other words, if I were to build a spaceship to optimize earnings, I would have only high passage rooms and freight, doing only jump 6s.

What did not I understand? In what my assumptions are wrong?
