Yes - I recommend reading StatRacket's analysis.
Cheers buddy!Here's the first page of my three part article on age and ranking
in men's tennis.
Unfortunately, we cannot say for sure what the average age of peak performance will be among today's players as the date of their career high ranking is still uncertain. However, we can look at the average age of career high of the top players in the past. The top 50 players of 1980 reached their career high at 25.74 on average. The 1995 top 50 had an average career high age of 25.02.
I suspect that the average age of peak performance will still be around 25, but players are now performing close to their career best for longer (or at least at older ages). For example, players like Ljubicic, Chela and Nieminen are performing well at older ages but aren't reaching new career highs. This phenomenon increases the average age of the top 100 but doesn't increase the age in which players peak.
