Varience per round

Does anyone know what the accepted value for varience/ round of 1,2 and 3 hands? If I am not mistaken 1 hand has a varience of 1.3 or so but I am not sure about the other two.

According to Peter Griffin

Each additional hand will increase the variance by about 0.5, so two hands would be 1.8 per round and three hands would be 2.3 per round. There's more information about this (as it relates to bet sizing) here:
