Tweaking OnDemand while stock rooted

I searched on Google for ways to tweak this governor for better battery life and I came across this

To bias ondemand towards battery saving, set high up-thresholds and higher sampling-rate. This way, governor polls less often and scales up less often.
Code:
echo "95" /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
echo "120000" > /sys/devices/system/cpu/cpufreq/ondemand/sampling_rate
echo "1" > /sys/devices/system/cpu/cpufreq/ondemand/sampling_down_factor
echo "5" > /sys/devices/system/cpu/cpufreq/ondemand/down_differential
echo "10" > /sys/devices/system/cpu/cpufreq/ondemand/freq_step

First off, let me say that I found this in a forum for the GS2, and that's where my questions come in.. Would these be safe to use on my GS3? If not, is there anyone else that runs the OnDemand governor that have tweaked these settings with battery life in mind? If so, what are your settings?
