I just had a thought, if X-23 is younger that Wolverine does this mean she can heal faster than he can??

how would that have any affect on how strong their healing factors are

Can't Daken heal faster than Logan for that exact reason?

Daken and Laura heal faster because their skeletons aren't completely blinged out with Adamantium. Age might play a role with healing factors as powers, but Wolverine is probably still rather young relatively, and given that he is still alive in many futures hundreds of years from now, his healing factor is probably still at its peak efficiency. Laura also might not have had her healing factor peak yet either, so there are a lot of variables here, but I do think I remember someone one in a comic or maybe a writer confirming she had a faster healing factor.  She is less durable though, so it balances out nicely. 

Daken and X-23 don't have as much adamantium in their bodies (actually, doesn't Daken have the Mermassa blade coating his claws? What doe that do?). The adamantium actually hinders Wolverine, because his body is constantly trying to keep the metal from poisoning his body. Wolverine with bone claws is actually stronger than with adamantium. 

Has that been suggested in comics before?

" Laura has stated she heals faster than the "old man" (as she called Wolverine), but aside from some atrocious writing by Rick Remender, Daken does not heal faster than Logan. "

How does that work? Why would Laura heal faster than Wolvie but not Daken? I understand that Logan has the adamantium implants which have been suggested to weaken his healing factor by a small degree, which may be the reason Laura, apparently, heals faster, but why would Daken not have the same advantage, do you think?
