If you're in the top 250 out of 1000, that doesn't make you average. By definition it's well above average. Moreover, the 1000 ranked players do not represent the continuum of players overall. They are all significantly better than the actual average, which is why they are ranked.
Great spin off on the word average here. It makes you average at table tennis. But we are talking about being an "expert". So 250 in England does not make you an expert at table tennis. Also if you knew what you were talking about then you would know that if I want to get ranking ( just for the ranking sake) I would craft my schedule in a way so I play weak tournaments just to get ranking. Ranking and expertise correlation is very flawed. Ask any athlete about this and they will tell you that there are a lot of players that would play weak tournaments just to get ranking. They would be even top 50 in the country but it doesn't make them experts.
