According to Ebisu, the real hard part is creating just the right amount of chakra you need and then converting it into a technique, since any extra chakra is "wasted" (which doesn't really make sense either, honestly). That's funny. That's actually the part that made the most sense to me. It's like a description of energy efficiency. An inefficient engine converts gas to locomotion poorly, so it's wasting most of that energy as waste heat. Meanwhile, an efficient engine will get the maximum amount of energy out of a gallon of gasoline and convert it into locomotion, wasting a much smaller amount of energy as waste heat.

That's how I think of using chakra. Sakura was highly "efficient," Sasuke moderately efficient, and Naruto highly "inefficient" at using chakra. Sakura converted the necessary amount of chakra into her jutsus, almost nothing wasted. Sasuke was middle of the road, but had a higher chakra pool and better jutsu. Naruto was terrible at converting his chakra into jutsu, so ended up wasting a lot of chakra to do the same things the others could do with less, but had a metric crap ton of chakra to throw at any jutsu.
