The deal with the Dr is quite loose. He pretty much does whatever he wants or whatever is convenient at that time.
If you want to donate the standard daily fee for general security work ($2500 PER DAY) you can ask for whatever you want and you'll probably get it. Otherwise you might get something, maybe, one day, possibly and sometime before you die if you're lucky.
If you do some research you'll see that the various companies fees for decapping/de-protecting and extracting data are quite high. For example processing 20 custom chips and/or microcontrollers can easily run to $80000 or more so the deal we are getting is very generous and we should be patient. I've said this almost word for word at least 10 times....
