Yes, that's a good part of it. That is why Quandrant is kind of useless. It can give you an overall idea of performance, but I/O will inflate the scores a lot. A lot of people have reported that certain ROM/kernel combinations feel much smoother than others that get much higher Quadrant scores. Also, you can overclock as much as possible, and it will make things smoother probably, but not affect quadrant scores *that* much. There's just too many factors to make it useful. All it's really good at is comparing is differences in a more controlled environment. For example, you can get a good idea of much faster a kernel is by running a quadrant score using both kernels, but on the exact same ROM, using the exact same governor, etc. Otherwise, you can kind of just forget Quadrant results.
