Ok, just wanted for you to be able to calculate in detail.
Look, here's all the details:

In your particular case, 5 in a skill in the IELTS can be different CLB, because each skill has different measures.
In your case, L, W and S are all CLB5, but R is CLB6. But, because CLB 5 and 6 both gives 1 point per skill, he will earn you 4 additional CRS points.
As I told you, the tool makes all these calculations automatically. Just wanted to be more helpful and teach you how to fish.
