I try to cover as much events as possible in North-West Europe, i.e. Netherlands, Germany, France, Belgium, Austria but I don't manage to do them all. This also includes challengers.
Besides, my focus is on women's tennis, so men's events have a lower priority. But when I have a chance I do them too.
Thanks, cool job, though you don't get to see much full matches. Why is your priority WTA?
