As mentioned before, I have raced in 36 knots sustained with gusts of 42 knots, kite, crew on wire and going full noise downwind. Have also raced many races in excess off 30 knots, never hesitated to fly the kite and survived / finished the races.

However the question is not what is the max you have sailed in but what is the max you would sail in if you have a choice...... As, What would be your max limit you would knowingly put yourself out in. And to make it realistic, with regular crew numbers and maximum sail area. Not a Tornado only under jib with 4 people on board.
