Assuming you're using a 1AS:2DS ratio: Since each battle takes half of the needed AS/DS, you'll be hitting the boss with a team that uses 20 AS and/or 40 DS. This will leave 10 AS and 20 DS, so you'll be regenerating 10 AS and 20 DS during the 10-minutes that it takes for the "Let go" button to appear. You should stop at the boss that you cannot beat with the team that uses 20 AS and 40 DS.
