Strict import doesn't matter about size of the imported file.
Strict means all verts and such match on their numbers.
So if you have 100 verts you need to have 100 text coords and 100 normals (If included)
Both the diffuse obj and AO obj MUST match those numbers!
AND the faces must match! That is the tricky part.
I'll need to test the different versions of TDW's program as I'm not sure how he's defining Strict at this time.
