Yeah, sorry. The nested city situation is tough to get exactly right…
The activity page data is displaying everything, regardless of whether or not the street is in a nested city. That’s why the numbers are different when you view the activity from your profile page (that view is not counting nested cities):
Paddington is a nested city. Just under its name in the top left, it indicates that it’s nested in Brisbane & links out to Brisbane.
A nested city is any city whose boundary exists entirely within another city’s boundary.
The next release will include the street’s city name below each street name, except on the city page.
