What I was alluding to was that SET may not be all that much of a cost saver, unless one anticipates a really significant taxi. On the flip side, doing a SET for a short taxi, getting near the runway, having to hurry up and start then T/O without proper warm-up time is more likely to cause engine wear/damage that would offset the fuel savings rather quickly.
