You don't read carefully.
Renowned scientist Maddison put Hungary in East European countries (I just took from his book), yes it is Central European country, but it doesn't matter for this discussion.
What is important is:
Hungarian GDP per capita in 1000 year, is $400, as in Balkan and East European countries, Greece, United Kingdom and Scandinavian countries.
If you think that Hungary had higher GDP per capita in 1000 year comparing with Greece, Balkan and East European countries, United Kingdom and Scandinavian countries, you think mistakenly.
Of course, you can try to do your research and confute Maddison, but it must be serious scientific paper.
