both cpuidle and cpufreq target the next state based on activity and
idleness thresholds.

if the algos add just enough to cross any limit that otherwise would not be passed, they can
have quite an influence.

especially if the performance of the 2 decoders is isgnificantly different.

Think about a thrshold-based tax system, if you want a (loose) analogy.
