Calling all Hill Experts

I would assume (since I don't use an altimeter), that the number is "gain above sea level", thus it would show a change up on your desk.

When you set the altimeter up, do you first dial in the altitude of your starting location, i.e. front yard?

spazz - operating on pure theory and no practical experience

actually you set your altimeter according to the book every morning pretty much so it would be based on setting it by the altitude where you live and then calculated on the inclines you ride. (did that make sense?)

and garage door openers and other remote devices, for that matter I have a wireless cycle computer and it took me the longest time to figure out why my max speed would often show ~ 48 mph .. uh, nooo... until one day when I noticed that the computer would go a bit haywire when I used the garage remote while on or near my bike.

Actually I was reading the book last night and the altimeter uses barometric pressure to sense altitude increases - sitting on the couch with no electronics I gained and lost 4' every time I raised the cyclometer! (levitation maybe?) but the gain could be right.....I live at 5589' and ride down that incline every morning when I go to work so that number may be very close to right.
