let me add one final point, namly the ratio of fore- and backhand speed. The key issue is that (smart) players tend to aim their strikes only on backhand side, because it is always limited to 65 points. I think that
a combined limit of 140 points and a related
general limit of 75 points
would be good option to fix this. Stefan Edberg, Patrick Rafter or Ivan Ljubi?i? are few examples for players with a stronger backhand. Another possibility would be to set a "distinctive characteristic", for example players with an excellent
serve like Andy Roddick (+ ... percent more points at serve),
footwork like Roger Federer (+ ... percent at speed),
forehand like Gael Monfils / backhand like Stefan Edbergs (+ ... percent more points at fore- / backhand) or
reaction like Rafael Nadal (+ ... percent faster auto-position).
These things would be an improvement to develop an individual style and in all imply a better gameplay at tour / online.
I don't think this got noticed the first time is was posted, but it's a brilliant set of suggestions and i'd second it any day
