The wording is a bit weird, but "squishing" here just means using a constant number (the normalization constant) and multiplying all numbers in a vector by it.

The wording is a bit weird, but "squishing" here just means using a constant number (the normalization constant) and multiplying all numbers in a vector by it. E.g: Multiplying [0,2,2,0] by 2 gives you [0,4,4,0], which is better distributed over the I3 distribution [0,2,4] (which goes all the way to 4). Any additional values that might get lost to rounding between 0 and 2 could be more easily restored that way. E.g. [0,1,2,2,0] would become [0,2,2,2,0] without squishing and [0,2,4,4,0] with it.
