how dry before tempering?

I split a green sugar maple log into staves today. What % moisture content should it get down to before heat treating/tempering with a heat gun?

Bow building dry. 9% to 11% M/C.  Tempering forces moisture out but too quickly for a green stave. You can strap the stave to a form in reflex and set it aside to dry and some of that reflex will remain when it's ready to work.
