Doesn't work like that.

A full backup is kept as long as any incremental backup depends on it. This is 
no matter what you have "Full Max" set to. So the full of 09/04/2010 would be 
kept until the incrememtal backup of 16/04/2010 is deleted.

Then both the full of 09/04/2010 and the incremental of 16/04/2010 would be 
deleted together.
