You hear this phrase a lot in BJJ, I think it applies to all martial art's really but it seems people are more conscious of it in BJJ. My question is at what point does drilling reach the point of zero return in terms of improving your game. One rough quote I've heard; It takes about 100 rep's to create the neural pathway for a new movement pattern and 3000-5000 rep's to fully ingrain the technique into the muscle memory and it make it subconscious. It will then take substantially more focused rep's to alter the technique. So if a guy drill's an armbar from guard 5 times each side per class and then goes for it 3 times a class in rolling and attend's class three times a week that will be about 25 rep's a week, which would then turn into 1250 rep's a year. So roughly the average guy would reach the point of diminishing returns for a common move like that after about three - four year's in to their BJJ jouney when they are pushing purple belt if not one already. From there on it would be a question of strategy, S & C and adding in other moves that would take them further, plus potentially also the fact that no two armbar's are exactly the same. Is this a fair assessment of what you can get from drilling? Or am I over/underestimating the importance of this phrase?
