We will be happy to describe it to you. Each newly credited career point has a validity of 28 days. This means all orders with all points result in your career level.
To example:
On 01.12. Jürgen orders for 300 career points (KP). These are valid until 29.12.
On December 2, Lisa orders for 100 CP. These are valid until 30.12.
On 03.12 Peter and Luise order for 500 CP. These are valid until 31.12.
This means that each new order has a validity of 28 days. On the 29th the respective points expire.
Therefore, it is recommended to have stable and healthy growth in the team. Through a continuous build-up and a natural growth in depth, you get to optimal stability and bit by bit more growth.
I wish you the best for your next career steps!
