Yes, I read your ramble. The operable statistic is number of

per number of launches - very simple and not included in your

OK. I note that you've avoided my question, which was
whether we you agree
with "The data says that in the period 2006-12 a German pilot
had much the
same chance as a UK civilian pilot of being killed or injured in
a winch
accident. "

So, I'll ask again - do you agree with that conclusion? I've
provided all
the data you need, and its source, and the calculation is
simple.

Whether you think that's a good "operable statistic" or not is
different.
I happen to think it is - because then we don't confuse
different reporting
of incidents.

There can be no doubt when an injury or a fatality occurs and
such an event should always be reported and recorded in
gliding developed countries. I think we can all agree that no
country will over-report death and injury data. Therefore the
only way that comparison of death and injury rates between two
countries could *not* be based on valid operable statistics is if
you were to believe that one country is under-reporting them -
which would be an interesting propositon to put to the Germans.
