Very fast shed?

So my ball python is in shed. His eyes started in-blue a mere 2 days ago (if not, less) and he's cleared up already.
Is it normal for it to be that fast? The humidity in his viv right now is 64-66%. Last time he shed (1 month 20 days ago) he was in-blue for twice as long, the humidity was the same and he shed in one piece.

Perfectly normal. He's just ready to shed quicker than last time that's all.
Some bps shed surprisingly quickly to the point where most of the signs are easily missed.

Yup! normal. Sometimes by ball pythons are blue *forever* other times I open the tub and there is a shed in there I wasn't expecting.
