It would be good to now a little bit more about the levelling system you have in the US (4.0, 4.5, 5.0...). What is it equivalent to (i.e. how good is a 5.0-5.5 player, like most of TW:s play tester's). Example: the Dutch had a system with A1=elite (tour challenge satellite), A2 approx. elite juniors and older tour players, B1= very good club players. Is there anywhere a player's strength and the points system?
