The only problem with that is that your plan might not work since there have been days when the BGs were full after 1 or 2 minutes. You don't know if your app is going to have problems, and if you wait to try, you may end up with nothing. My suggestion is to get a BG as soon as possible and if you get a low number, see a GET CM and ask if they will change it to a later number for you. There are reports on the thread of people having success with this, although there's no guarantee.
