Good points, and I don't know the answers. I wish I did, and in this case the old saying "your guess is as good as mine" definitely applies. Your guess is probably better, as I don't remember when or why I came to the conclusion I did, and I probably trusted someone else's judgement. Life was so much easier with SH1 - teleport to your patrol zone with appropriate loss of fuel, teleport home when done. Unless you misjudged, in which case you just got a message: "Not enough fuel for return voyage".
