Layer adhesion of PLA-CF is better than for regular PLA?

Hi

According to the data sheets of Bambulab, layer adhesion of PLA-CF is supposed to be worse compared to regular PLA.

According to the filament guide, it is 13.8 kJ/m2 for regular PLA but only 7.8 kJ/m2 for PLA-CF.

This is against my experience. I printed some thin-wall parts (wall count = 2) and from my experience, PLA-CF is significantly stronger than regular PLA.

It’s ok for me, it is an additional reason to go for PLA-CF. However, I would like to understand the behaviour.

Does anyone have similar experience regarding layer adhesion?
