It is indeed unclear. The resolution is that the absolute rogue-wave-height isn't the measure of extreme, it's the rogue-wave-height relative to the typical height. This is explained in TFA if you read carefully. > Scientists define a rogue wave as any wave more than twice the height of the waves surrounding it. The Draupner wave, for instance, was 25.6 meters tall, while its neighbors were only 12 meters tall. And of course this makes sense.
