Get the instructor to take you to mangalore with a nice long runway and demonstrate failure at rotation.
In my day, that would be called practicing bleeding. Like mixture cuts on take off. Potentially dangerous and unnecessary. If I recall correctly, it was at Mangalore that TAA or maybe it was Ansett, that pranged the first Viscount and killed someone. I think a check pilot pulled an engine at rotation and control was lost. Pulling an engine at rotation is a recipe for disaster. Not all instructors are competent. Leave that stuff to simulators.
