No, the cost to basic strategy was not addressed because it is not relevant. These strategies are for use specifically in tournament situations where you need to achieve a net win on the current hand -- as in right now. These situations are typically of the nature that if you don't win now, you have no chance later. The final hand of a round is the most common example of this, but you can find also yourself in this situation with several hands left to play. The cost to basic strategy has no bearing in this situation, nor does it to a large extent in most tournament situations requiring playing deviations.
