I was under impression it meant to give you 10% extra attack in future

I upped mine, but it's still 9%...

The attack bonus increases over a few eras. For example it provides 8% if it's in the Modern, Post Modern, or Contemporary Era.

For Tomorrow and the Future it provides 9%. The other stats for the building increase with each era.
