If it were solely based on the ratio of gasses detroit would just pump fresh air into the exhaust instead of spending a grand on a catalytic converter.
And with this info as I have stated before, any leak in your exhaust system will benefit you on your emissions test.

But that seems to go back to the original question. The observed readings were identical for both tests.
Do you think that, based on the size of the leak + the accuracy of the readings yielded an accidental co-inky-dink of identical readings?
