Selfin,
Capt Kremin (#7676, 24th 0211Z), the posted tracks do not take account of wind. For the 197M constant magnetic track coordinates: text, kmz.
These tracks whether they are magnetic or true. May all be inconsequential if the new Altitudes found to be 12000' or less. The B777 fuel burn and TAS would be totally different making the current search area too far away now.
