Reply to "Elevations from various sources"

If the same source is used for both Start and Finish locations, does the accuracy of elevation really matter?

If I have a drop of 10 meters from Start to Finish, does it matter if I peg my Start elevation at 2100 meters or 2140 meters, and finish at 2090 meters or 2130 meters, respectively? If I use a GPS that calculates elevation through barometric pressure, I get a different elevation at the same location on different days. It can vary from morning to evening, if the weather is changing.

I think that if the same source is used for both locations, it doesn't matter how "correct" it is. It is the relative difference we are looking for.
