cuddieheadrigg,
Forgive me, but I can't help feeling as if we're being asked to take part in some kind of consumer survey by an organisation that has only a passing interest in the subject, that has insufficient time/inclination/ability to phrase all its questions with intelligible syntax, demands yes/no answers, and which may have an agenda it is unwilling to reveal.
Am I being uncharitable?
JD-EE,
Re "gentle descent unlikely": yes, admittedly I do occasionally lapse into tongue-in-cheek understatement.
