Do you really think that their clients fully represent the range of
farming businesses?

They are likely to be large estates, contact farming and share farming.
Probably some of the most efficient, and some average or worse.

I'd expect that their sample is biased towards the
upper end of farm-business sizes, and other sources, such as Nix, are
pretty clear about the effect of farm size on costs, warning that the
agricultural press often ignores this in the figures they present.

Indeed. However they also report that one man bands and family farms are
not costing in their full labour, by a long way. So they must have some
family farms too.
