Not good.

Well, the actual value is calculated from $_POST['edit'] values and  
#default_value . If there is a _POST value, then it overwrites the  
#default_value .

There are at least two solutions:

a) You change $_POST
b) You add a #value to the form element in this case. Have you read the  
documentation that you should never use #value? This is the exception.  
However, be extremely cautious what you set here, it'll be sent back to  
the user.
