That's true, and anyway, 2 + 1 is nearly not faster in average than 3 + 0 (as soon as 60 moves are played 60 * 1 second are one full minute). :)
Furthermore concerning the 'sprinters': paradoxically their advantage is even bigger in longer time controls than in short ones because longer time controls allow to berserk by still having enough time to win nevertheless and get 3 points instead of 2 only (and if they lose they have immediately the opportunity to win again - they can play at least twice as many games during one tournamnet as the average 'snail' by berserking). :)
