That's where I ended up too. Although, I'm going to end way higher than I did last week. I'm currently in 2nd with my current active assignment and one more to go and I'm already 1000 above where I ended last week.
What I've been doing is preparing for assignments before starting them. In this case, I happened to get Make Electronic components, Make Drills and Make Couches, which all paid off to the tune of 1500-2500, so I started some of each. Since they're all components of each other, it worked out well. I didn't start the assignments until I already some available. Items can be ready to collect when you start an assignment. Just don't collect them until you start the assignment and it will count, so it's not like you have to start completely from scratch. You can prepare yourself well in advance. Cheetah tokens help too. 🙂 I had to be very careful not to collect something by accident, which seems to happen to me all the time just navigating around the city.
With what I currently have planned, I should end around the 10,000 mark instead of the 6000 mark I was last week.
My only complaint about it would be this......
You only get 10 assignments that you're able to do. If you accidentally start an assignment that is impossible, such as this week was upgrade 3 paris zones and I don't have any paris zones that are not already maxed and don't want more. I started the assignment by accident, canceled the assignment, I went from 10 assignments to 9. If you don't make any progress towards that assignment, they should just stop the assignment and put it back into the assignment queue. Not create a new assignment and take away one of your assignments. I did that once last week and once this week or I'd end higher than I'm going to now.
It's nothing that can't be worked around or being very diligent with which ones you start, but I'm not liking how they did that part of it. There should possibly be some way of passing on an assignment that is not possible of completing. I don't want more Paris, London or Tokyo zones since they can't be upgraded for speed-up tokens. I already have the 10 of each required for certain Landmarks.
