Have Patches changed the value of selling Science?

[realpolitic]

I've always found selling techs a valuable strategy. Although I've come up with a mathematically rigourous formula for how profitable selling science before the patches, I want to make sure I can come up with the right formula so I can create a thread about the strategy for the Democracy game.

1.29 changed science's value, both in the way difficulty levels changed the beakers to research a tech, and in how valuable techs are to buy/sell. Techs are worth MUCH more under 1.29.

But, since the demogame uses 1.21, I assume your formula would still apply. Except for a few tweaks to the individual value of techs (which wouldn't change your formula anyway), I don't think there was much change to science in pre-1.29 patches.
