I don't think that's a true statement at all - do you have any evidence to support that?
As for extrapolating the wingover argument into exceeding all limitations, that seems a very black and white position to take ie 'If you are going to break one rule you may as well break them all' and not representative of any pilots I have ever flown with.
Do you have any evidence to support your assertion that it is only 1%?
I am referring to a flying culture of which a wingover is but a part.
My last comment was obviously hyperbolic, but if someone is prepared to break one rule, they will certainly be prepared to break another. How many they choose to skirt is academic, comes back again to culture and culture certainly has an effect on safety.
When eventually something goes wrong it will be the cumulative effects of all the little percentages that have unexpectedly added up.
