It's been my dream for years to have a system that would predict ETA not based on pace so far, but using an algorithm that takes into account the altitude profile and average speed on the ascent/flat/descent. The average pace works well on the flat, but it always made me laugh that Suunto tells me that I have 4h to the end of the route, because I've been going to the summit for 4h, while now it will only be descent and it will probably take 2h

But I know that it is not easy to implement and rather poor chance that someone will introduce it. In addition, I learned to estimate times myself based on distance and altitude profile. But one can always dream
PS - I know you don't want to make any plans or promises, but just casual and non-committal - any approximate dates when more or less we can expect new navi functions?
