PIG Week 4

I just finished the first four weeks of the Performance Improvement Guarantee program and it was tough. When you start, it says it's going to be hard and it was. This week will be a recovery week followed by another test to reset my CP30. I'm excited and worried at the same time. I want to see how much I've improved but I'm scared because the CP30 will reset the level of effort for the next four weeks. The last four were tough, how much harder will the next four be?
