It is a goofy problem. I'm sure there's some explanation involving the manufacturer of the industrial equipment.

It caught me, we would up about 1.5" short which meant a spacer strip to sit the second floor walls on. I blocked those joists solid underneath and then nailed the edge of the sheathing into that... it must be similar in strength to landing on the rim joist itself. I'll let you guys know if my house tips over.  d*

that is the case with all T&G subfloor I've worked with. There should not be a strip less than 16" wide according to APA which means you usually have to add another row of sheathing to your materials list.
