How Fast is Sage Bijuu Mode Naruto healing?

[Xāvî1]

Almost instant

Leave him be, he's a troll and narutofanboy.

Is it just me or the way this picture is drawn, but did Naruto lose both his arms here? Next panel he has them back.
This would obviously prove his healing is far beyond that of anyone else.

He gave kakashi a new eye, he should be able to do more to himself

That's different.

Can you imagine him growing an entire arm out of the palm of his hand onto someone else?
Besides, blow off his hand with the sun/full moon mark on it and you think he can still keep doing that?
