It is generally agreed upon that it takes 10000 hours of deliberate practice to get to a level where you are an expert at something, do to some handwavy math, you can interpolate good to take roughly 2000-3000 hours to become good at something.
At that number of hours played, we'll assume an average of 2.5 minutes per play due to retries and etc. the lower end for that would be around 48000 plays and the higher end would be around 72000 plays. Furthermore, the ratio of deliberate practice to regular play will vary amongst players, so for the lower bound for good would be around 48000 plays and upper bound somewhere around 90000-100000 plays.
Keep in mind this assume an average level of "talent", and as such people who are really focused, have really efficient practising, or know exactly how to analyze their own play might have a lower lower bound. Thus, as a really rough estimate, to become "good" in an absolute sense requires around 30000-100000 plays, and to become expert, could be anywhere from 50000-infinity plays depending on various variables.
Good in a relative sense can probably be modelled somewhat by a gamma distribution.
Based on this chart
http://paulbourke.net/miscellaneous/fun ... adist4.gifand with a value of B of perhaps 0.75, let's take the best player as having a 10 on the X axis, to have half of his absolute skill, you'd need to roughly be in the top 2% of the active population.
Basically, this is shitposting done well.
