Yeah, that was my take on it as well. But how would you interprete the 3 or 4 o'clock setting then? That would be maxing out the Rumble.We refer to it as clock setting on a 12 hour clock. The knobs don't go all the way to the bottom, so we usual say 7 is as low as it will go. 9 is where the pointer is pointed to the left at where 9:00 would be on a clock dial. Am or PM or European time doesn't apply. So running at 12 is the pointer straigt up.
Everything is possible of course but that would be taking it pretty extreme, at least to me.
