To be perfectly honest, it depends on the game. There are very few twitch games now where 2 frames would make a difference in competitive outcome. E.g. games like overwatch, paladins, smite aren't really twitch games so that delay doesn't make a huge differences. Or rather, other elements of skill far outweigh whatever small difference that delay makes. You might have a case if you're talking about esports teams at the top tiers, but if you're that good, then you'd likely be able to make a living from it and would have your own gaming machine.
