The most efficient route will most likely have a clover shape. That's why you'll end up changing communities and returning to the same neighbourhoods in one route.
If you use a navigation app to go from stop to stop, please check the direction of driving before leaving to prevent detours. If you already do that and still notice backtracking, please share your route with us so we can take a look:
Press the '⠇button' (next to the Edit button)
Select Share route

Since you know the roads best, it's really helpful if you could say which stops are wrong, and why.
