^Indoors, a player can usually cut it finer. You probably wouldn't see such a drop shot hot streak at the Australian Open for example.
Yeah that's true, but I still don't see Jerzy replicating this consistency with such a low margin in the future. He may keep up the form today (and I hope he does) but his play is very much dependent on the extent to which he is 'in the zone'. This also shines through in the way he is gaining tempo in rallies with the cross court forehand, he is hitting it very hard without too much spin, this is a shot that will cease to become worth the risk once his level drops a little. I hope Janowicz can become a strong player, but I don't see him getting good results consistently playing like this, the margins are too small for the modern game and he can't serve 80+ % first serve for ever.
