Mass airflow of a 13b??

i don't understand the question.
because a turbo will alter the airflow of the engine so each and every turbo is going to push different volumes through the engine. unless you are asking what the starting airflow of a 13B-T is without a turbo on it.
all i know is that historically people have used 135lb+ turbos on 13B engines that had enough response to set records. does a 13BT factory engine pull 135lbs? no. but will it support that? yes, with the right fuel and EMS.

Or is it a really rough estimation.

Doubling the displacement is accurate for the displacement variable. However, the results of the equation are rough because you will need to guess at the volumetric efficiency variable.

i *think* they are talking about the S5 na in that graph, well and the MSP. anyways its the first VE graph of an NA engine i've ever seen from Mazda, we have the two NSU engines, the R100, and the JC cosmo engines
