One feature people repeatedly ask about is the ability to see statistics for a selection of Garmin Activities. It is actually possible by using the search feature.
Let’s say for example I want to see the statistics of all the running activities in july 2015. I first enter that as a search
Then in the statistics page, hit the type button until the term Search appears. It will remind you what the search term was, and then the statistics you see are only using the currently selected list:
This will be the case for the other stats page as well, here for example I show a scatter plot of Pace versus HR for the running activities of July 2015
Another useful application is to run statistics on a specific activity type, for example all the skiing activities as here, I show how much elevation gain I achieved each month in backcountry skiing. You can see more about skiing here
It is limited though by the current search syntax of ConnectStats, which if there is significant demand, I may extend. Just let me know.
