You can be in a hover with far more than 25 kts of wind. - what have you done wrong toohigh?
Surely the court can accept dictionary definitions of hover - it's not rocket science - it's what a Kestrel does when hunting, it's what a waiter does when waiting for a tip - if it's not stationary, it's not a hover.
A perfect example, as happily witnessed several kestrels doing whilst I was playing golf today - they coped admirably with a good 25 knots of wind much better than I did! On a much larger scale, submarines also establish a pure hover prior to launching missiles.
