As I understand the process scheduler, it there's no real difference between, say, nice -10 and nice -20 in most cases. On my system, the highest-priority threads are some kernel threads, and they're running at -5 right now; thus it would make no difference if I reniced a process -10 or -20, as they would pre-empt even those kernel threads either way.
Thus the trying of different levels. Try, say, -20, -5, 0, and 5 multiple times, and wait a minute or between switches. See if it's actually the process of renicing that spikes it, or just the fact that you're prioritizing that process.
