Hovering up and down

ATV's weather report tonight reported that the relative humidity today "hovered between 76 and 94 percent". I wonder if they know what "hover" means - if we see a helicopter hovering, we expect it to stay at approximately the same height above the ground. If its height varied between 75 and 96 feet above the ground, perhaps "yoyoing" would be a more appropriate term - or even "oscillating" if the variation is repeated regularly. Why don't they say "fluctuated" instead?
