A recent steady climb on foot in the Alps from 1300m to 2000m displayed correctly in the Elevation Plot window, but the Total Ascent data field registered only 536m. No changes in Baro pressure, no intermediate ups and downs, so what's going on? Looks like it could be an Etrex30 software error.
I had been suspicious of Total Ascent readings while riding here in the UK, but put it down to all the undulations that occur in this part of the world (Chilterns). I was used to Total Ascent on my Casio wristwatch altimeter (which measures once every 2 minutes) disagreeing with my VDO bike computer/altimeter (which measures much more frequently) - after all, a chap can't have too many gadgets - but the Etrex result seems to be an ERROR plain and simple
Anyone else noticed this?
