Good point. I never seen that in courts though, but I guess it is a valid point. The key is that mini tennis is useful if it allows you to forget about other variables involved like depth/pace/movement etc and just concentrate on what is important in mini tennis, which is contact and feel. If you are still spraying the balls all over and just leaning and lounching for every ball... then probably not much benefit.
But why a need for lot of topspin? Gravity pulls the ball down anyway, it's just about controling the pace (through slower swing speed).
