My own notes and guesses were eerily close to WotC's in many ways - I drifted a little lower on defense than they did was the main difference I saw.
I don't have a copy of the math I wrote up before, but I believe I'd suggested
Attack - Median Level +5, AC attacks usually 2 higher than other defenses, Max Range Level +2 to Level +7 (I didn't make AoE any lower, though)
Defense - Median Level + 12, but high variance by type,AC average 2 higher than others, and often dipping lower.
Damage - I was _very_ fuzzy on this, operating mostly from instinct and a vague 'Well, something like 1d8 + 1/2 level'
I was wrong about solo hit points - didn't know it would all be 8 no matter the role, and didn't expect the x4 for Heroic only. To be honest, I'm a little weirded out by the 8 no matter the role, since you still have soldier solos having huge defenses or lurkers who can have -5 to attack them with concealment - while brutes are the easiest to kill.
