To be honest, Bogomolov's ranking attests a current crisis in men's tennis in positions 30-50. The guy shouldn't have entered Top 50. Think that players like Carlsen or Arthurs never advanced to the Top 40...
What attests more of a current crisis for me after rank 24, or even after rank 8, is the age of the players at some ranks : I'm amazed by the poor rankings of the players of generations 87(except Djoko-Murray) and following ones, and the good rankings of old generations (83 and before)
... and the worst part is that I compilate the ranks of the players at each of their birthday, and each generation seems worse than the previous one at the same age ... except generation 92 with Tomic, Harrison, Marti, Kudla, Duckworth, Mitchell and many others ... which is an exception among the young generations but not at all comparing to old generations.
I think it's a catastrophe for the future of tennis, and it would be even worse if tennis used a 2-year ranking system as the current top-guys ask (except Fed)
