Thank you Jane
With regards to the time- it's the same with the US Open, isn't it? the night match thing- and RG are going the same way. At the US Open, I suspect braodcasting rights play a massive part.
It won't happen at Wimbledon, due to being in a very built up area, and annoying the 'nice' neighbours
. Even 11pm is pushing it. (Though I think RG is in a similar part of Paris, isn't it?).
