As others have pointed out, the whole point of this range is to preempt the opponents, not constructively reach game. In fact id say theres no point to playing a 3 point range for a purely preemptive NT opening, might as well play 8-11. I dont think this argument extends to other ranges (even 10-12 vs 10-13) because a lot of those will be "constructive" hands whereas a lot fewer of the 8-11s will be our hand. If I were to play 8-11 fav I would open any balanced 8 count and would upgrade some 11s (field openers) into 1-suit.
