but the reason he says it has to be before round 4 is that as the rounds go on, george gets stronger just like the other zombies. so if you try to kill him on early rounds he will have less health. so there may be some truth to this but it would still probably take a good 15mins of continuous knifing. also i tried this out earlyer and i found out that know matter how hard you try you are going to go down a lot. but this might be better because its easier to knife george while you are down for some reason. just 1 person knife him till you go down then keep knifing him really fast to kill him faster this way.
