The 2nd test has worked, multiplayer game, I am on ship construction 1, the other race is on level 4, I ask for:

ship construction
ship construction
ship construction

And get all the Tech levels up to level 4.

There is another tricky issue about this, you never know, for what level the other race is asking for unless you don't know on what level it currently is.

If race A is on Physics 2 and it asks for:

Physics

Then it would actually ask for Physics 3, right ? But race B does not know that, it could be Physics 1 also which makes a lot of difference in the values of the trades.
