Update on my test:

After some 5, 6 odd hours running, when everything is minimized, my results are these:

It seems that it "wants" (however you phrase) to stay at around 6%, however, it jumps up to the fifteen and 20s (maybe once every 20 seconds). I'm refreshing at one sec in the process viewer. Also, more rarely It jumps to the 50s-80s. Can't examine anything more closely, cuz school calls, but later I shall.
