Great tool! I am generally a big fan of the concept "VAM", for I am one of these unlucky persons not having a power meter. I's a really good pacing tool on (primarily long) climbs, and in some cases even better than the power estimation data fields you can get, since it generally is less spiky.

Very useful tool! This is the second best method after powermeter for pacing on hill climbs and also to train using power on hill climbs. On my bikes without powermeter I use this APP to estimate my power output on the hill climbs. I use it for grades bigger than 5%, then my speed is below 15km/h, means wind resistance can be neglected. I made a chart based on my weight + bike weight and used tools on the internet (bikecalculator) to correlate VAM to power out put.

Useless! Neededs is something that shows VAM as a 3s or 10s average. This one takes a long time to settle on a average value. Perhaps on long climbs acceptable but useless on shorter ascents. Also starts with a value that is not zero, like it should be. It reads -300 or something like that.

Thanks for your poorly researched feedback. I'll try to explain your issues. - The intended audience for this datafield are riders, who are unsatisfied with the stock vertical speed datafield of Garmin devices. If you find it useless, please use the stock datafield. - Averaging time can be chosen in the App-Settings. Try to set the filter length value to 1. This will result in a three seconds averaging (given the three seconds sample reate), as you wish. However, VAM as a performance metric doesn't make much sense on short climbs, thus the default value applies more smoothing and higher accuracy. - The settle time depends solely on the averaging filter length. The altitude sensor resolution is limited, thus accuracy requires longer filters. Everybody is free to configure it in the settings. - If you see a non-zero reading while stationary, please watch the altitude value and you will see that it changes as well. This is most likely the result of the automatic GPS-based calibration of the barometric altitude sensor after the initial GPS fix. The datafield correctly processes the changing altitude. I've never seen this after the calibration is done. The datafield can't distinguish if you're riding and elevator or if the sensor calibration is running, it just processes altitude changes over time.
