^^^I think this is often where issues on the board occur. Those in the tennis teaching industry tend to use certain terminology to mean certain things and it's okay because all those on the inside understand them. When talking to those outside the industry we have to remember the terminology may not be so well agreed upon and understood.
For example, Sureshs uses the term "late" to describe the contact in relation to the ball (where a coach would use on the rise or on the drop) as opposed to a coaches use of "late" to describe the contact in relation to the body (i.e. a contact behind the plane of the body).
