These were direct before and after tests that I did multiple occasions. Nothing else on the vehicle changed and I went to the same exact pump at the same exact gas station and did the tests when traffic was low to insure accuracy. At the time I didn't have any instrumentation hooked up to the vehicle except for the onboard mpg computer which always showed a higher MPG than normal with the HHO but I ignored that because the computer always over reported the mileage with or without HHO. I did fuel economy tests by filling up the gas tank all the way to the lid and measuring the amount used and recorded the miles traveled. I admit the sample sizes were small(30 miles at a time) and once I find the time to get the system on my focus up and running I will be running longer tests with an ultragauge hooked up and I will try turning the system on will running down the highway and see if the mpg changes instantly. I'll definitely post my findings. I'm just trying to find an explanation.
