Friday looked full, so three stops went to\n// Saturday instead - and the moment the 50 units left, Friday dropped to 49\n// against Saturday's 93.

Both, always - being merely nearer is not\n// enough on its own, and this is the part that took several attempts to get\n// right, so it is worth writing down why.\n//\n// The obvious design is \"move any stop to a day whose route passes nearer\".\n// Tried three ways - crow-flies to the truck, crow-flies to the day, real road\n// distance to the day - and every one of them made Florida worse, by 45km, then\n// 103km, then 108km, while each individual move looked like a 5-15km\n// improvement. The reason is that Florida runs every truck at 95-100% of its\n// cube. There is no slack anywhere, so a stop arriving on an \"easier\" day\n// forces that day's two vans to be re-cut, and the re-cut costs far more than\n// the proximity gain. Proximity to one stop simply does not predict what\n// happens to a full day's route.\n//\n// Where the tail really is back-loaded there is slack by definition, and the\n// arithmetic works. That is DC's case and the one this was built for: Saturday\n// carrying 93 units against Friday's 49.
