Make the extension amount something you can set via command. Then run a potload of tests. I ran WAC with all the extensions set to values between .5 and 1.0, in increments of .25. That is 3 cases for each extension and I varied 4 different extensions. 81 tests and you then look at which ones needed the fewest total nodes to solve _all_ the test positions...
