Determine Ability Scores. Generate scores as for a 1st-level character, applying racial modifiers. Then increase those scores as shown on the Character Advancement table in the Player’s Handbook, with increases at 4th level, 8th level, 11th, 14th, and so on.
Tellingly, 11th level would be your first level in the Paragon tier. It is possible that when you hit a new tier, its something of a minor template with a suite of benefits, one being additional attribute boost.
Thats just a guess, though.
EDIT: Ah, already brought up. Thats what I get for posting before getting to the end of the thread!
