The total sum of the points you have accumulated over the past 4 weeks is the number that counts.

If that number is bigger than 100 points you get silver status, if it's bigger than 800 you get gold status, 3000 for platinum status and 7500 for diamond status.

For example, your 4 weeks report looks like:

Week 4 - 3 points

Week 3 - 7 points

Week 2 - 39 points

Week 1 - 50 points

Total : 99 points (That is bronze status)

Now, if you would collect more than 4 points in the following week you would be silver, but if you manage to collect, say over 704 points, you would be automatically gold.

Now, you might ask why 4 or 704 points if the total sum is 99. That's because the "Week 4" drops out, "Week 3" becomes the new "Week 4", etc. So your report would look something like that:

Week 4 - 7 points

Week 3 - 39 points

Week 2 - 50 points

Week 1 - 4 points (or 704 points)

Total: 100 points (or 800 points)

That's basically it!
