That's a powerful reminder that the simple propagation models upon which
most "band opening" predictions are based are just that: they often have

I could not agree more!! On this occasion I think that Kevin's signal
followed two paths to Scotland, initially down to South America and then
single hop chordal F layer from S.America to here. As that path closed the
second became dominant, another single hop path but skewed north of the
great circle path. IF I am awake (03:00 local time <g>) I usually hear
Kevin via the northern skewed route at this point in the solar cycle, and
not hearing other ECN signals does suggest a single hop chordal path, F
layer possibly E layer or a mix.
