Post smog test failed

I recently had a test performed on my 94 z28 Camaro..
I failed on 15mph ho ,I passed the 25 mph test.
Passed on all other tests .
I went to the referee and had them test my car..
On this test i Failed the 25 mph and passed the 15 mph.
These tests were done within a week of each other.same tank of gas etc..why the difference in tests ,and which one was correct..

Welcome to the forums! Are you taking it in with a cold engine or are you giving it a good run down the interstate before you drive in?? Makes a difference.
When we had emissions checks in Atlanta, I lived a mile from the inspection station. I failed the first one, and the guy who ran it, told me to run it a few miles on the interstate before I brought it in to get it to "good" operating temperature.
