Why is th UV island normal baking margin calculation by dividing the normal map resolution by 128?

Thanks, jlampel, for the helpfull tips concernning the preparation for a successfull normal map baking! Is the division by 128 for the calculation of the UV island normal baking margin based on the normal map resolution just a value found out by testing or can it be justified mathematically? I know that 128 can be expressed as the result of 2 raised to the power of 7, but maybe there's an explanation beeing a little bit more detailed.
