...Dude I think your gonna be fine, in fact the "force" is tellin me your ok. They always do a lot of writing of useless bullshit. They do some testing there for temp and maybe ph levels and stuff but as far as I know the actual testing for the things that make life bearable they have to do in a lab. Most times they get sent out by courier.
You crossed one big hurdle already, they didn't reject your sample for dilution, and you must have cleared the other pre-testing soooooooo...now its the best part.."the wait" the wait is just excruciating. See, I got caught once as a CDL driver and I had to take 7 more after that so I know the routine. By the way you describe it, I would be really surprised if you failed. Don't sweat it, and let us know how it turned out...Good luck!
