I wonder the same thing. In normal hives, there are bees of varying
size, but one would winder why they would make cells that tight. I seem
to recall 4.3 cells having been the smallest cells reported in EHB
natural comb. Natural comb can sag, however, and cells change shape, so
I don't know.
We must keep in mind that there is a range of 'normal' behaviour and
there can be extremes and outliers as well as observation errors.

I was looking at Bob's numbers and thinking that 17% seems unlikely --
on the small side at least.

I don't understand that. Until recently, standard foundation has all
tended to be above 5.2 in North America -- AFAIK.

Those numbers are
857~=5.2,
520~=6.6,
814 ~=5.325,
540~=6.5
