Some interesting information about great players was found, for instance:
- They played 45-50 singles matches per year plus 15 doubles matches, which was below average for these ages.
- They practiced around 10 hours per week, which was below the average for the group, and two to four hours less than the top 12-13 year-old players.

100 matches an year for 10-12 year old? You cannot be serious.
