@stefan-kersting that is true, there is actually more accurate (IMHO) algorithm already developed and published in S3, but since we got a lot user feedback that it gives too little steps (when users got used to get plenty, the more accurate was not appreciated, may be target group issue too) there has not been a decision to push it to other watches. (offtopic, I’ve been moved to other tasks quite a while ago so I’m not too active in this forum, sry)
