Overspined VS. Underspineed

Hey Fellas,
Below are tips to improve broadhead flight.
Please try to explain this to me. I'm having a heck of a time understanding this.

if an arrow is underspined that means it's too weak, correct. Why would you increase bow weight or decrease arrow spine when it's already underspined. Am I mixing this up?

And if an arrow is overspined, wouldn't that mean it's too stiff, which would require a heavier draw weight or decrease in spine or broadhead weight.

3. Arrow underspined, increase bow weight or decrease arrow spine or increase broadhead weight.

4. Arrow overspined, decrease bow weight or increase arrow spine or decrease broadhead weight.

any help would greatly be appreciated.

You are correct.
If your broadhead groups impact right of your field point groups, you're underspined.
Impact left, overspined.

Underspined = weak arrow shaft

If you need more details on tuning, let me know.
