For everyone using what turn you win by = Bracket...

Just curious, I don't know the turn orders for said brackets. For instance, think I read somewhere for bracket 2 expect games to go to turn 10 and up. Bracket 3 around Turn 7 and etc. Is this a good baseline?

If my deck wins through aggro are we talking what turn I reach enough damage to kill everyone? This is obviously while goldfishing, but if it takes my deck wether it be dragon tribal till turn 8 to kill everyone, or aristocrats past turn 9 is that indicative of it's power level?
