Default Serve NOT scalable

The talk is often around his work for beginners ("Tennis in 2 Hours" etc), but I am interested in the work he does with, as you say, top juniors and pro's.

That's why I would be interested to hear Oscars thoughts on my points above.

Cheers
Greetings,
I believe Bruce Elliot has a recent paper on the subject why serve is NOT scalable.
I did NOT see the full paper,I believe I saw an abstract

Abstract
The importance of the flat serve in tennis is well documented, with an abundance of research evaluating the service technique of adult male players. Comparatively, the female and junior serves have received far less attention. Therefore, the aims of this study were to quantify the flat serve kinematics in elite pre-pubescent, pubescent and post-pubescent female tennis players. Full body, racket and ball kinematics were derived using a 22-camera VICON motion capture system. Racket velocity was significantly lower in the pre-pubescent group than the two older groups. In generating racket velocity, the role of the serving arm appears to become more pronounced after the onset of puberty, while leg drive and 'shoulder-over-shoulder' rotation mature even later in development. These factors are proposed to relate to strength deficits and junior players' intentions to reduce the complexity of the skill. Temporally, coupling perception (cues from the ball) and action (body movements) is less refined in the pre-pubescent serve, presumably reducing the 'rhythm' (and dynamism) of the service action. Practically, there appears scope for equipment scaling to preserve kinematic relevance between the junior and senior serve and promote skill acquisition.
