Madara's chakra was too low to turn his Sharingan on when Hashirama shanked him lol therefore I think maybe chakra levels effect the sensory ability.. as Sasuke can only sense Naruto thanks to them being transmigrants and Naruto having such massive chakra levels thanks to Kurama. Also @Shadowflame, 4yrs and 9 months is the youngest we have seen a kid join the academy, training to become a ninja. the general graduation age is 12yrs old for every kid who isn't special, but average. So your point of Nagato STARTING Ninja training at 10yrs old and then 3 yrs later being able to help defeat A Sannin Shadow clone(half of Jiraiya basically) being unimpressive is just wrong. He had only 3 yrs to learn to be a ninja and train that way then he was on his own with Yahiko and Konan. When most kids can't accomplish that like he did.. From going from a village boy to basically a Chunin in 3yrs.
