Don’t want to start getting too far into it or splitting hairs but regular visitors to Gatwick will know that the difference between making E or FR can easily add quite a significant amount of time onto your taxy time depending on the traffic situation. I completely agree with your point that it’s peanuts but if you’re interested in the minutiae of specifically choosing Flap 3 in order to save 8kg fuel but then you miss a turnoff that then costs you more than 8kgs fuel in the process then that’s missing the bigger picture IMHO.
