The world's most empressive skylines: new method

Hi!
I created a new method to estimate an impressiveness of skylines all over the world. I used the data from Emporis and Skyscraperpage sites. I take into account only top 50 buildings from each city and only built buildings. I summed up the heights of top 50 buildings (R1) and separately summed up the heights of top 25 buildings (R2). Than, to appreciate the city with very high buildings as compared with the rest of buildings in a city (such as Seattle, Los Angeles), cities with downtowns, which look more impressive as compared with the cities with scattered buildings with the same height (such as Sao Paolo, Curitiba, Rio de Janeiro), I intoduced a coefficient: for R1 -1, for R2- 2.
The Formula R= (R1+R2*2)/3
Look what I made.
