x in that chart is days since start

AFAIK points are indeed calculated when reported but rewarded when the WU has been confirmed. That's why I chose VGTU, a reported task seems to be confirmed right away. Maybe they don't need to check, I didn't look into it. You have a valid point here. But I like to start with as little variables as possible. Stay tuned, I'm making progress and will report here for sure.
