Better indeed; but then it does not closely match the description just
above, which explains there are columns numbered from 1 to 4, the last
of which is _conditional_ (not merely optional) based on the fact the
"country" has multiple rows or not.

PS: I did not check whether that condition is checked or even if the
current content complies.
