I wrote nothing about these 0,1%. If in NBA we have 450 players, and if I wrote that they are better than 99,9% players on whole world, it means, that I need to find only 450.000 worse players to be right ;-)
And even if You can find 450 other players better than NBA players, so it means that I need to find only 900.000 worse players and still I'm right.
And I think many millions people play in basket ;-) So I'm right.
Most users on this forum compare they teams to NBA teams (or at least to top teams in their country). But in NBA we have only 30 teams. So they should compare their teams to NBA teams only if they are in top-30 in world ranking in BB (or let's say top-100 if we include very strong teams but not from NBA). If they arent' in top-30/100 in world in BB, they should compare their teams to worse teams in real life.
And less than 1% of all players on world are professionalists. 99% of them are amateur. And therefore most of teams in BB should be compared to amateur teams in real life. And amateur player has "normal" job and play in basket for fun, not for money, and has very weak skills.
If we want to use BB scale to descrie players in real life it doesn't mean that 20 is the best player in NBA and 1 is the worst player in NBA. It means that 20 is the best player on the world and 1 is the worst player on the world. So if Michael Jordan has skill = 20 in BB scale, then the worst player in NBA has 18, maybe 17. Other values are for semi-professionalists, amateurs and school players.
