Very true. The result of this for people making strategic decisions regarding their lives is that if the field puts high value on positional factors, you should only engage in practice in that field if you have natural talent. For example, being in the 93rd percentile of basketball players (or startup founders) isn't going to make you millions of dollars (The value is in being better with respect to others, not with being good in absolute terms. Only one person gets to be the best.).

But being in the 93rd percent of public equity investors will make you mightily rich.

If you don't practice, it doesn't matter how much talent you have. Not only won't you be the best, you won't even be good.

At least in the context of this study, amount of practice is the dominant term.

For most purposes, being the best isn't necessary, only being good.
