You're welcome. It's one of those geeky things that are neat to know. And with the increasing popularity of smart phones many brewers have something capable of running a spreadsheet with them when they brew. That's why I started formating my spreadsheets in a way that makes them easier to use on small screens.
Don't worry about +/- 2 or even more. I'm concerned about +/- 10+. If you want to go all the way, just take a guess on the expected error of the measurements and enter this on the right hand side. This way you get confidence ranges on the restults.
