Stair Climb Activity

I'm training for a summit bid of Mt Rainier this summer and have been doing a lot of stairs (mostly in my office building but also some outside stairs up a bluff that is near where I live). I had been using the Hiking activity that I modified for my purposes but then over the weekend discovered that a Stair Climb activity was added a few updates ago.

Has anybody used Stair Climb? Has anybody else bumped into any of these issues? Overall, I find both to be weirdly limiting.

Stair Climb doesn't seem to track total ascent on the watch or within the activity on Garmin Connect (Hiking does).
Stair Climb doesn't show Training Effect in Garmin Connect (though it does calculate it for Training Status)
Hiking doesn't let me add Flights climbed to display on the watch but I get overall count of flights for the day in Garmin Connect
Stair Climb doesn't seem to calc distance traveled in miles while Hiking does (even in doors)
Stair Climb gives weird reporting on flights. On the "My Day" card it shows 117 for an activity. Tapping through it shows 147 floors. On the All-Up My Day Floors Card it shows 133 up.
