Tech Progression Formula?
OK... I've been playing for a while, but I'm embarassed to say this question eludes me...
When trading tech with human players, you often exchange for even value (research points). However, I have a hard time (maybe I'm too lazy) figuring out the Tech Progression Formula for tech cost.
In the research queue, your current level is displayed, along with the cost to reach next level. But the cost researched to get to those levels are not displayed.
For example, if I were to trade 4 levels of ship construction, could I calculate how much value (research points) I have already spent, based on the cost displayed to reach the next level?
Or is there a spreadsheet available that shows the costs? As always, I appreciate any advice!
