That makes a further thought occur to me - ability to land downwind at-all in any given aeroplane should probably be a further aspect of the research question, and downwind landing performance.
Just envisaging *possible* research outcomes they might come out with a series of "success" bands:
Red - You won't succeed
Amber - You'll get it on the runway but almost certainly go through the hedge
Green - You have a good chance of success.
Possibly defined by a combination of aircraft performance, runway length, and wind.
(Or not, I am conjecting - "it's a damned fool idea under most circumstances" is also a valid research outcome, even if I'd not word it quite like that in a paper for Aeronautical Journal.)
