I think you're worrying too much. Just set it and forget it. The impact is minimal. Losing up to 20 minutes a day is frankly meaningless.
Thanks.
Ummm... I like his answer better than mine. Really, if your in this for the long haul (and I hope you are), then 20 minutes/day ain't squat. Remember, all of us here just do what we can do, but we got Klutz,Malusa,and a couple others on our six. You'll be fine.
DUmmies think we reached our peak :)
