If I may make a suggestion about the research for a LPS, the uni and arch levels do not necessarily have to stay at 5 as you get higher and higher fort levels.
When you begin to construct, or think about constructing, level 5+ fortresses, first calculate how much building one level of uni and one level of arc will raise your points by, and then calculate how much slack that'll cut for your points through arch lowering the cost of the next fort.
I found that building 8 lvls of uni and arch is still making the exchange of points favourable to the player building the research against players just building the fort at 5&5, not to mention how much time that'll save and resources on other buildings.
Just another thought, hope it helps,
