With all due respect to the OP, your phone is heavily modified(arguably). While this thread has provided great discussion for inquiring minds, I do think your opinion on this matter carries less weight due to this. It is kind of like saying your truck gets 5mpg better than everyone else's and then we find out you have a different ECU, airbox, etc. and that you use a different fuel blend not readily available to others.
Anyway, I think the Android operating system is a great example of "chaos theory". A very short explanation is the first few sentences from Wikipedia:
Chaos theory is a field of study in mathematics, physics, economics and philosophy studying the behavior of dynamical systems that are highly sensitive to initial conditions. This sensitivity is popularly referred to as the butterfly effect. Small differences in initial conditions (such as those due to rounding errors in numerical computation) yield widely diverging outcomes for chaotic systems, rendering long-term prediction impossible in general. This happens even though these systems are deterministic, meaning that their future behaviour is fully determined by their initial conditions, with no random elements involved.
IOW, the "builders" of the android OS have no clue how developers will develop apps and therefore cannot determine the final outcomes as to how the app will affect the OS. It is those last words..."random elements" that throws a wrench in the spokes. There are lots of "random elements" running around inside our phones once we download everything we can get our hands on.
So, in theory, your initial posts and subsequent follow up posts are true(modified phone notwithstanding). In reality, I will use ATK due to the unpredictable potential chaotic nature of how apps interact with each other and the OS.
