Investigation of Trade Income

[therother]

Whilst compiling the Forum Index, I've noticed that there isn't really one good thread where we discuss all the facets of trade (or if there is, I haven't yet found it). So I hope that we can collate all our experiments, observations, and data here.

This first post is a placeholder for the summary of our investigations, to be written when we have some. Which is why this post does not say very much of use!

Will post -- or in some cases repost -- some data and observations in a bit.
