Default Resistance to bellying

I’m asking about the relative resistance to bending between new, old and torrefied wood (I say “resistance” rather than stiffness in case there is a difference). I’m thinking specifically about spruce soundboards bellying with string tension as the years pass. I’m assuming “identical” prior to becoming 80 years old, or torrefied.
And secondly, whether that elasticity reaches a limit over time where providing it doesn’t break, it will not distort further.

Thanks in advance for any opinions you’re willing to share,
