I believe that this information is not complete at the moment (at least for November-December) due to databases migrations, so something could be missing.
However, if the number of nodes is growing even on 10%, that’s mean that the data is more distributed among them, at least on the same 10%. In some regions it maybe even more - if your location has more competitors, then the speed of the node is starting to play a significant role.
For example - you may check out this thread:
The difference between nodes in the same country (but which have distance between two compared locations) 300GB vs 1.49TB.
