Dang 926! Do you wait late game to declare or something(beyond 1725)?
The game I just finished had the largest REF I have dealt with so far, 321. This was on Rev and still took 26 years(played on epic so double that for # turns) for the king to land all his troops. I even produced bells from the outset, though my sentiment got plenty high enough at 1702 to just do it(over 80%). I suppose I could have gone and wiped out the Spanish/French to get some free cities and veterans but it didn't seem wise considering the distance from my colonies.
