The installation guide says "between":

"If the system memory is between 128MB and 2GB, the size of the swap
partition will be between the system memory size and twice the amount
of system memory. For example, a system with 1GB of system memory will
have a swap partition sized *** between 1GB and 2GB ***.
If the system memory is higher than 2GB, the size of the swap partition
will be a between 1GB and 2GB plus system memory. For example, a system
with 4GB of system memory will have a swap partition sized *** between 1GB
and 6GB ***."

You could always have a pre-script generate the 'correct' swap size (based on your own formula), put it in a file and include that file in the kickstart file...
