As well to to the other responses you wish to even fill in mind there are a pair of batches of all equipment and there would possibly perhaps be no longer any requirement for the relaxation but the vehicles themselves and personnel to traipse speed to speed.
An example of a more ambiance expedient calendar than you give would possibly perhaps be Canada->Monaco->USA->France, to illustrate. With unit A equipment travelling Canada->USA and unit B equipment travelling Monaco->France.
The calendar is stuffed with compromises between industrial interests, weather, logistics, and plenty others, and plenty others. Possibly it is no longer actually ultimate but it is undoubtedly beyond being optimised by ‘upright attach nearby races help to relief.’
