Profile's "Biggest Climb" stat shows descents?
I noticed that my Profile's "Biggest Climb" stattistic is actually based on a descent segment.
It would seem the function is set up to grab whatever segment has the biggest elevation difference, regardless whether it's actually a climb or not.
I would suggest modifying the query to exclude any segments with a negative percent grade. Further, as others have mentioned elsewhere, this stat should be limited to segments with 2% grade (or steeper), since anything 'flatter' would be an insignificant "Biggest Climb".
This topic may have been indirectly mentioned elsewhere in the Support Community, but I wanted to give it a dedicated post.
