2020 aluminum deflection?

[canadian]

I can't seem to find it anywhere.  If a 2117 is at 400 what is the 2020 at.
Thanks.

if you dont mind me asking is there a formula to figure arrow deflection? thanks

No formula; you either measure it on a spine deflection machine or look it up in the Easton charts; available on their website.
