It is really impossible to say. There are just too many variables to consider here. For example:

Some CrossFit gyms have more offerings than just the traditional WoDs. E.g.: your friend might have be mixing mobility training, strength, cardio workouts.

Also, your friend might have latent injuries or have to stop for a week or so due pain/soreness. It is just you are not aware of those.

Some people are anatomically more fit for certain exercises than others. I'll skip any days with dead lifts because it is an exercise I cannot compromise proper form. So, I protect myself even if for many CF coaches it is just temporary weakness I could improve.
