Real emissions tests are measured in Grams per Mile, not percentages and parts per million. They also take about six days to complete, vastly different than your 'quickee' ASM tests. Also, the test numbers on the supposedly "treated" engines are no different than what I've measured with my 5 gas analyzer on identical vehicles that I -know- have been no where near your ceramic monkey jizz.
All your tests show (not prove) is that there was a change in the samples taken at the exhaust pipe, the effects of which could be that the engine was allowed to warm up more on the later tests versus the earlier tests.
