Indeed, if you're doing extreme free diving, it would make more sense to breathe a more depth-compatible (nitrogen-replaced) mix at the surface before diving, no?
Then your lungs (and blood) would be full of a safer gas mix at depth.
I'm not sure if any of the deeper gas mixes are safe to breathe at surface level though? I think so?
