I think there are reasons that cigars offered in a box may be more consistent than 5 packs, 3 packs, etc.
There is more volume to marry the flavors/aromas in a full box.
Before boxing the cigars are sorted for color consistency, etc and any held out can be put in packs where presentation is not as noticeable.
I have noticed this with Habanos but can't say it has made much difference in the taste.
