Great idea, and the spreadsheet makes it even better. Sure helps me to identify holes in my GHB. Mine is worked off a pair of nearly identical GHBs for the wife and I. I plan on bugging in if at all possible. I work 3 miles from home, but take a lot of trips also and have set up my ghb up for 3 days, 2 people.
