I don't think that all practice needs to be precisely situation specific. Exposing a 3rd teamer to some pacey bowling in a dimly lit hall may not realistically represent what he can expect to face come the first round of matches, however it can serve other purposes. Although the bowling did not appear to be played with much confidence, such a session can boost the confidence of a player when he returns to facing bowling of a lesser pace. Also just how easy is it to recreate English conditions in April whilst indoors?
