I'm just wondering if this is normal and I'm just looking too hard or if there might be an issue. I've been using the autove guide and have got to the end of adjusting, but I've noticed something odd. It seems if I log on the trip to work (~30miles, highway and backroads mix) when its in the 70s or maybe low 80s it comes up with most cells at about .98 or so. But if I log on the way home from work when its in the 90s or a tad higher, I get results more like 1.02. Is that normal/acceptable?
