One public dataset that I think people should analyze is how competitive rating changes based on number of events you participated in.
For example, in programming competitions the history ratings of everybody is public: http://community.topcoder.com/tc?module=AlgoRank http://community.topcoder.com/tc?module=AlgoRank.
One of the most well known competitive programmers is probably tourist: http://community.topcoder.com/tc?module=MemberProfile&cr=22263204&tab=alg http://community.topcoder.com/tc?module=MemberProfile&cr=222.... He started at a rating of about 1200 when he was 12yrs old but took him over 5 years to increase it by 2000 points. For everyone that kept at it for equally as long, you can see a similar trend in trajectory. The only difference is the slope at which their ratings increase.
(The ratings probably mean nothing to you, so for some calibration, people with a rating of about 1500 can easily pass a google interview, and I think a fresh CS grad with no practice will probably start at around 1000. Which probably gives hope to the average CS grad since even for the world's best, it took them about 10 years to get to where they are.)
I just thought this was a nice way to quantify growth vs practice.

They all started at a "green" or "blue" rating (i.e., no prior training) and it took all of them a bit of time to hit "red", which is the arbitrary point you can start calling them an expert.
