Hola! Never heard of [Server1] or [Server2], but that's probably because most servers have "RO" or "Ragnarok" somewhere in their names. I'm sure heRO is capable of outperforming them regardless anyway.
Aaaaaaanywhooo... The square root of 3 is 1.73205081. Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object. Heavy water is normal water, but with two deuterium atoms replacing the two hydrogen atoms. Just fyi.
Welcome to heRO and enjoy your stay. \o/
