I made a simple spreadsheet to calculate the effect that Spire Civilian Leaders have on your AI progress over the course of a game. All you do is update the captured, destroyed, and lost posts cells in the hour that they occur, and then fill drag down the list, and you can see the effect that it has on future AI progress. You can use it to eliminate the guesswork from planning out how fast you need to capture or destroy posts to have a gain by the time you plan on trying to finish off the homeworlds.
Hope someone else gets a little use out of it like I have. =)
