You'll figure it out the same way you figure out a throttle stop ratio. Set the Genie up according to a guess, see what the car runs. Make a somewhat large change to the Genie, and see how much that changed the ET. You should then be able to get pretty close on the third pass.

Some friends have run static plates to keep their cars above 10.00 when bracket racing, and it seems like every change of 0.100" to the bore size would change the ET about a tenth.
