I just realized that Eren's claim about the Ackerman power giving the user the experience of all other Ackermans may have a hole.

Mikasa is tough but Levi clearly has Titan killing skills that she doesn't. We have never seen her use his beyblade attack.

The only answer I can think of is that when the Ackerman power is activated, it gives the user a screen shot of the current accumulated skill level of the Ackerman clan, but the pathways are cut after that. Then Levi may have raised the bar on the Ackerman clans skill level while Mikasa was growing up.
