Hello, I was doing some testing and had weird results. Please tell me what I should expect in these scenarios.

1) I have Deaf and I use the Keen Hearing syringe
2) I have Hard of Hearing and use Keen Hearing syringe
3) I have no hearing trait and use Keen Hearing syringe
4) I have weak and use Strong
5) I have no modification to strength and use Strong on a new character
5a) What should happen when I get enough strength to auto-get stout?
6) I have no modification to strength and use Strong when I have trained to 9 strength

Thanks, it would help to just understand the intent.
