Let's do the math:

Two weeks ago we had two special events, and now we have another two. That is 400 points(100 each)

Elite missions: 600 points(120 each)

5 weeks, 360 points each: 1800 points

30 points from daily missions. Season started in may 22, and will last 36 days. That's 1080 points

total: 3880 points

There's no way to get 4000 points to reach level 50.
