New SMART barometric algorithm
-
From software update announcement:
-
Initial threshold reduced to 2 m (previously 3 m)
-
Meter-by-meter measurement after the initial threshold
-
New air/water filtering (wind, rain, humidity, friction)
-
Elimination of false ascent and descent spikes
-
Improved altimeter accuracy and stability
In very strong winds, the problem still persists, but the error is much smaller. In this case, it was about 250m too high. According to the Suunto Vertical, 1185m – it should be around 900-950m.
I’m generally satisfied; previously, my ascent totals were often over 1000m higher than the actual total. But there’s still room for improvement.
It can be clearly visible at the upper part of the mountain, where the wind was definitely the strongest, that the graph is very jagged and hence the inflated results.

By the way, I find it to be foot by foot rather than meter by meter when the watch is configured in imperial units. One foot = 30.5 cm.
