I think he meant that Tribes were taking 278 turns to train on Normal gamespeed. I think there's a bug in the hammer cost calculations for settler type units, who have since vanilla had a very special code for that.Current SVN Normal game speed is not 1000 turns any more. It is the same Number of turns as the Old Epic 2000 turns. You have noticed that right?
If you want tribalism to show up around when you would normally expect from the old "normal", then play Blitz. Blitz is the New "normal" game speed.
You have looked into the GameSpeedInfos file right? And into your NightMare Handicap file too? Much has changed.
