Fuel check question

[FED 387]

Jim --I think that what you are describing is beyond the scope of most if not all of the NHRA people that are probably technically challenged to do anything other than the rudimenntery type of fuel test-- by this I mean ask the brand of fuel ,insert the testing probe into the container and press the button/s and read the results, then compare the reading to the acceptable range allowed by NHRA for that brand ---it ends up being a GO -NO GO scenario pass/fail whatever--now that I think about it I never really have seen the tester cleanse the tester probe from one sample(racer) to the next-- have you??? This action alone might possibly comppromise the next fuel batch results because of trace samples left from the previous fuel especially if that next sample is o so close to being borderline to begin with
