The reed has a crack and will completely break if you plink it a 
little, retuning is futile. If it goes slightly flat (a few cent) 
retuning makes sense. I'm not sure what causes the flatness, but i 
think it's a result of micofissures. The reed material becomes 
structurally weakened.
In your case though, almost a halftone flat and still going flat, the 
reed is gone.
